I would venture a guess that as you don't EXPLICITELY
initialize the timeout.tv_usec value to be
within 0 to 999999 it may get some system dependent
sometimes random, sometimes fixed value (the joys of these
stack-allocated "automatic" variables..)
For short: Smells of UNINITIALIZED PARAMETER DATA.
