 This happens periodically, and the only effective workaround seems to
 be to reboot the machine.

 It looks like a kernel bug, but we are not very sure about that.
 We should at least figure out (if possible) a simpler way to reproduce
 the problem.  My guess is that if we repeat forwarding FDs via unix
 domain sockets some resource leaks in the kernel and it eventually
 triggers the problem.
