Module Name:    src

Modified Files:
        src/tests/lib/libc/sys: t_ptrace_fork_wait.h

Log Message:
Ignore interception of the SIGCHLD signals.

SIGCHLD once blocked is discarded by the kernel as it has the
SA_IGNORE property. During the fork(2) operation all signals can be
shortly blocked and missed (unless there is a registered signal
handler in the traced child). This leads to a race in this test if
there would be an intention to catch SIGCHLD.
