:I couldn't find a commit that I can relate to a fix for that problem,
:neither in -release nor in -devel.

:lock on a vnode which is being locked by tcsh, which is in state ttywai.
: Guess on which tty: ttyp5. Seems like a deadlock situation.
:Is there something I can look at? I could try to get a dump tomorrow,
