I suspect vi's not handling an EAGAIN error return.  I get this on
-stable when ripping a cd with grip/cdda2wav.  Are you doing something
that runs at very high priority when it happens?  Judging from the
comments in /usr/src/sys/errno.h, it could also be that there is a
resource deadlock and vi is not translating the errno correctly.
Anyway, pending a fix in vi to handle retryable errors, the workaround
is not to do whatever it is that you're doing at the same time.
