b28055517e Implement a completely new getwork scheduler. 
Stage all work from the one thread, making it possible to serialise all requests minimising the number of getworks requested or local work generated.
Use a pthread conditional to wake up the thread whenever work is removed to generate enough work to stay above the watermark set by opt_queue.
Remove all remnants of the old queueing mechanism, deleting the now defunct queued count.

31e43944bc Do not use or count or use the getworks submitted which are simply testing that pools are still up. This was increasing share leakage and making stats not reflect real work. 2012-11-24 10:58:46 +11:00

2d35ac2567 Track all dynamically allocated memory within the work struct by copying work structs in a common place, creating freshly allocated heap ram for all arrays within the copied struct. 
Clear all work structs from the same place to ensure memory does not leak from arrays within the struct.
Convert the gbt coinbase and stratum strings within the work struct to heap ram.
This will allow arbitrary lengths without an upper limit for the strings, preventing the overflows that happen with GBT.
