I think it's probably in the noise.  And anyway I don't think the
connection rate of ipoib CM is particularly important.  And we can
always optimize ib_find_pkey as part of the longer-term plan to get
rid of ib_find_cached_pkey.

If you want to tackle more of the cache elimination plan we discussed
that would be great though.

He seems to be saying that it's OK to introduce a window where things
fail spuriously.  I disagree.
