Execution hangs or stalls unpredictably.
To recreate the problem:
1. $ for seq `900`; do echo localhost >> hosts.txt;
done
2. $ gcc -l pthread -o tping tping.c (tping.c is
attached)
3. $ while true; do strace -f ./tping 300 hosts.txt >
/dev/null 2>&1; echo -n .; done
4. Observe that execution stops, hangs or slows down
(while the said process is in ptrace_stop, I think).
Of course, when not straced, all is well.
Understandably , a production code isn't going to be
straced, but still ...
I've seen this behaviour on x86 2.6.16.16, 2.6.17-rc4,
FC5, SUSE 10.1 etc. Is it normal?
I'm fairly confident that my code is bugfree :-). If
not advance apologies.
Thanks

Oops. It ought to read:
$ for i in `seq 900`; do echo localhost >> hosts.txt;
done
Rest remain the same.
Sorry for the trouble.
Thanks
