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. > Zsh, actually.

The shell doesn't appear to have a bearing. -- Doug White | FreeBSD: The Power to Serve dwhite@gumbysoft.com | www.FreeBSD.org
