a4ec961ecc We can queue all the necessary work without hitting frequent stales now with the time and string stale protection active all the time. 
This prevents a pool being falsely labelled as not providing work fast enough.

	- Launch a new instance of cgminer with --bench-algo, and

	- Once it completes, either successfully or because of a

7158f9f9ed Add automated benchmark of the CPU hashers 
The --algo switch now accepts the "auto" argument.

    When "auto" is passed to --algo, cgminer starts by benchmarking
    all the CPU algorithms it nows about and picks the fastest.

    This is useful for benchmarking, but also for folks who run
    cgminer on a large number of heterogeneous computers because
    it saves them from having to configure each instance optimally.

    Caveat emptor: depending on the platform, some algorithms will
    fail with "illegal instruction" (e.g. via padlock code on non via
    platforms, or SSE4 code on non SSE4 platforms).

    To protect against this, cgminer runs the benchmarks in a child
    process. The crash, if any occurs in the child, and the parent
    marks this algo as "fails" and continues benchmarking the next
    algorithm.

    Unfortunately, this safeguard is only implemented for Linux
    because I have no clue how to do this on win32 (nor access to
    a win32 box).

Option lets user specify a command <cmd> that will get

    subsequently gets piped directly to this command.

    This permits smart batch monitoring of the miner by a
    baby-sitter log parser while retaining the full benefit
    of the curses interface, e.g. when running cgminer under
    screen.

    Doing the same thing is possible using advanced bash
    redirection paraphernalia, but it is somewhat of a pain,
    especially when running screen'd.

    This option makes things more straightforward.

0fe22d8d94 Revert "Only update the thread getwork queue count if it actually results in a getwork request from the server." 
This reverts commit 2e607d44f2.

The count looks far too difficult to add up with this change since many are queued generically.

da06a348d0 The work length in the miner thread gets smaller but doesn't get bigger if it's under 1 second. 
This could end up leading to CPU under-utilisation and lower and lower hash rates.

1536e085da Increase efficiency of slow mining threads such as CPU miners dramatically. 
Do this by detecting which threads cannot complete searching a work item within the scantime and then divide up a work item into multiple smaller work items.
Detect the age of the work items and if they've been cloned before to prevent doing the same work over.
If the work is too old to be divided, then see if it can be time rolled and do that to generate work.
This dramatically decreases the number of queued work items from a pool leading to higher overall efficiency (but the same hashrate and share submission rate).
