[#MDEV-15670] unit.my_atomic failed in buildbot with Signal 11 thrown

What I observe looks like a glibc bug. For me (ubuntu xenial) it crashes as following:

#0  0x00007fd1becd430d in nanosleep () at ../sysdeps/unix/syscall-template.S:84

#1  0x00007fd1becd425a in __sleep (seconds=0) at ../sysdeps/posix/sleep.c:55

The solution is to upgrade builders. A workaround is to make threads joinable (which will make code better anyway).
