New submission from Antoine Pitrou:
The C setitimer() function supports intervals with microsecond resolution.
However, Python's setitimer() takes a float and then converts it to a C `struct
timeval`, which can round down to zero. The consequence is that the timer is
disabled (timeval == {0,0}) while the user asked for a one microsecond timeout.
