Hm.  I took your modified version of my test script and added to the end:

print "i, ", i

And I get plenty of errors...

Hm.  strace tells me that this is what is happening:

------- begin included strace output
gettimeofday({996940586, 982012}, NULL) = 0
gettimeofday({996940586, 982154}, NULL) = 0
gettimeofday({996940586, 982295}, NULL) = 0
gettimeofday({996940586, 982435}, NULL) = 0
gettimeofday({996940586, 982576}, NULL) = 0
gettimeofday({996940586, 982718}, NULL) = 0
gettimeofday({996940586, 982859}, NULL) = 0
gettimeofday({996940586, 976989}, NULL) = 0

rt_sigaction(SIGINT, NULL, {0x400bbb50, [], 0x4000000}, 8) = 0
rt_sigaction(SIGINT, {SIG_DFL}, NULL, 8) = 0

i,  55
) = 59

------- begin included strace output

So my `gettimeofday()' sometimes returns a decreasing value.

Hm.  So I suppose I should report this as bug to debian...

What should I do with the bug report that I filed on sf.net?

Thanks for your help, Skip and Roman!
