By "hang" I meant forever.

The problem is actually that our automountd processes keep dying.

If automountd has died on your system, you can get the phenomenon.

The thing is that in the situation we are discussing, there seems to be
no real reason for cvs to be examining the local version of that
pathname, since it is supposed to be a remote pathname.

I.e. in the case of:

cvs -t -d :ext:address@hidden:/home/cvsuser/cvsroot checkout cs498/a2

There seems to be no reason to expect to be able to open any of the
components of /home/cvsuser/cvsroot (presumably some sort of failure is
handled okay as part of the "checkout" operation), since they are just
specifying the remote pathname, not a local pathname.
