We went round and round on irc about this a few weeks back.  We pinned it
down to a bad error check in nvi.  Unfortunately the fix was non-obvious.
There's a read() that needs to check for EAGAIN and loop back around on
the read.  If someone wants to take a crack at this, the offending read()
is at common/cl_read.c line 266.

I'm running tcsh and was able to reproduce on a 4.6-REL box a while back.
The shell doesn't appear to have a bearing.
