>Description:
waitpid(pid, &status, 0) doesn't harvest a child process when
used in a program compiled with -D_REENTRANT, linked with libc_r.a
and run from cron.

The program forks. the parent waits for the child using waitpid(pid, &status, 0).
the parent times out the waitpid with a sigalrm. the child sleeps and
then exits. the waitpid call times out. The problem occurs only when the program
is run from cron, compiled with -D_REENTRANT and linked with libc_r.a
