timeout a process

[iapain]

Hello,
I am trying to build and infinite loop handler in python 2.4 on windows
platform. The problem is that i want to create a process and forcely
kill/timeout after 2 sec to handle infinite loop in a gcc complied exe
on cygwin. something like below

os.system("mycpp.exe") # this exe is compiled with g++ and having an
infinite loop

I wish to terminate this after 2 sec. I've tried Watchdog and deamon
thread.. but nothing seem to work here.
