 Replying to [comment:11 walter]:
 > Hmm. Still froze after 4300 seconds.
 was that with clock()? i would expect that
 time() cast as int should fail semirandomly in the next 1000 hrs
 time() as a float should be ok providing the all code  that uses it is
 also ok

 the elegant solution is to replace all code
 while t2-t1<x wait
 to not wait if t2 < t1
 because t2<t1 only if an int has overflowed
