Hmm. The wait-for-input loop in the stats collector assumes that
if it gets EINTR, it should just retry the poll() call immediately.
Which AFAIK is correct. I think you're looking at a kernel or libc
bug here --- somehow the EINTR failure is recurring continuously.
It's probably time to ask about this on a FreeBSD-specific list.
