I just wrote a little utility which will force a timeout in
any application. The usage is very simple, you just run:
$ ./t0 15 <command> <args>

instead of
$ <command> <args>

The first line is equivalent to the second, with the addition of a call
to alarm(15) being added in the beginning of the <command> entry point.

This utility can be very usefull to avoid hangs in any tests, without
having to modify every source files.

The code of t0.c is POSIX, so it should work on any compliant platform
(tested with Linux and AIX).

When
$ ./t0 N <commandline>
is executed, the system behaves as if only <commandline> had been called
(ex: the 'ps' utility).

Here is a patch to the Open POSIX Test Suite, which will make use of the timeout utility into the Makefile.

The result will look like this:
conformance/interfaces/pthread_mutex_lock/3-1: execution: PASS
conformance/interfaces/pthread_mutex_lock/4-1: execution: HANG
conformance/interfaces/pthread_mutex_lock/2-1: execution: PASS
conformance/interfaces/pthread_mutex_lock/1-1: execution: PASS
conformance/interfaces/pthread_mutex_lock/5-1: execution: PASS
