    Well, we made all those lockf changes if people will recall.  It's almost
    certainly related to them.

    A ktrace would help.  I don't know if it would provide enough information,
    but it would definitely help.

:I'm seeing a similar lockup here with postfix-2.1.1, and kernel/world
:built yesterday with fresh source. However, it's not a usual lockup;

:The ps command in DDB showed that smtp process is stuck in `lockf' state.
:I didn't have time to write down the backtrace, but I can do it on request.
:The postfix in question is built on 13 May, and it used to work fine
:until I upgraded the kernel on 30 May. I'm going to rebuild it to see if
:it's reproducible, after backing up the old binary.
