With strace, when running 500 concurrent mem-hog tasks on the same
kernel, 33 of them failed with:
strace: ../sysdeps/nptl/fork.c:136: __libc_fork: Assertion
`THREAD_GETMEM (self, tid) != ppid' failed.
Which is: https://sourceware.org/bugzilla/show_bug.cgi?id=15392
And discussed before at: https://lkml.org/lkml/2015/2/6/470 but that
patch was not accepted.
