 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.
