Hmmm, I wonder if I should have tested this patch longer,
in view of the trouble I ran into testing the new patch?

Hmmm, while testing this patch, a couple of my servers got
stuck after ~30 minutes or so, like this:

I tried to capture a perf trace while this was going on, but it
never completed. "ps" on this system reports lots of kernel threads
and some user-space stuff, but hangs part way through - no ceph
executables in the output, oddly.

I can retest your earlier patch for a longer period, to
see if it does the same thing, or I can do some other thing
if you tell me what it is.

Also, FWIW I sorted a little through SysRq-T output from such
a system; these bits looked interesting:
