It's a restorecond bug.  restorecon acted as if watch descriptors
could never be reused.  They weren't on old kernels and it's possible
they are reused now.  Restorecon was fixed.

a change in the kernel caused a buggy userspace program to break.  I
know how to put the kernel back the way it was, but I don't know if we
call this a regression, you guys tell me.
