Follow-up Comment #1, bug #49014 (project make):
I've had a couple of hung makes in the last couple of months where I've
noticed a prominent number of zombies. I see my from-git make from
2016-06-11, reporting itself as 4.2.1, has HAVE_PSELECT=1 in config.status and
imports that symbol from glibc. The hang has always been deep in a big build,
I think after I've suspended and resumed the build with SIGSTOP and SIGCONT to
a large process group. Neither time did I find anything tractable, feared it
might be a kernel bug in:
Linux swiftboat 3.2.0-4-amd64 #1 SMP Debian 3.2.65-1+deb7u2 x86_64 GNU/Linux
Guess I should try strace()ing the daunting number of make processes next time
and looking at the signal masking in /proc. Sorry for the lame me-too.
