A patch for nanosleep

[H.J. Lu]

Hi,

I have forwarded a few emails regarding the nanosleep bug in glibc. I
am enclosing a testcase and a patch. Basically, the Linux kernel
doesn't really ignore SIGCHLD for nanosleep. We have to block it
in glibc if it is ignored by the process.

BTW, I didn't change linuxthreads. I am not sure what it should do
with the ignored SIGCHLD.

Thanks.
