In the assert()s take advantage of the fact that string constants
("string") are effectively of type 'const char []', which when used in
an expression yield a non-NULL pointer.
An assertion that should always fail can thus be formulated as:
assert(!"fail);
An assertion where a text message should be added to the expression can
be written as such:
assert("message" && expression);

Use non-blocking connects, and a select() call to wait a predefined
time (5s by default, but configurable with -timeout) for either
success or failure. This allows much more connections to be tried
per time unit.
Based on a patch by phantomcircuit.
