Vadim originally intended 5 milliseconds, he only read the parameter wrong.
Then noticing, that the parameter is actually microseconds, he iirc decided to
leave it as is because the discussion at that time seemed to lead to the conclusion, 
that a simple yield would be optimal in lack of some sort of detection, and
the select with 5 us seemed closest to that.

At least on AIX it looks like the select with 0 timeout is a noop, and does not
yield the processor. There was discussion, that other OS's (BSD) also does an 
immediate return in case of 0 timeout.

Minimum select(2) delay is 1 msec on AIX (tested with Tom's test.c).

So, what was the case against using yield (2) ?
