in reply to synchronized sub-routine call

sleep has seconds resolution.
Time::HiRes has fractional seconds resolution.

Oh, but if you want the previous function to continue running, and then time out, look at signal handlers: $SIG{ALRM}

See perlipc. Here's an example: 

eval {
        local $SIG{ALRM} = sub { die "alarm clock restart" };
        alarm 10;
        flock(FH, 2);   # blocking write lock
        alarm 0;
    };
    if ($@ and $@ !~ /alarm clock restart/) { die }

subone();
usleep (100); #sleep for 100 ms
subtwo();
usleep (100); #sleep for 100 ms

    unfortunately flock() won't work on win32.
    i'll have a lock a the corresponding win method
