Unexpected soft update inconsistency

:2) I built pkgsrc/firefox on my *other* DF installation (also on
:  the same disk) and got the same 'write error' just after
:  'leaving directory <foo>'.  *But* there was one big difference:
:  when I rebooted and ran fsck there were *no* errors found on
:  the filesystem.  I restarted the firefox bmake from where it
:  stopped and got a second 'write error'.  I rebooted again, ran
:  fsck again, and again it found *no* error.  (This DF install was
:  last updated on April 25.)
:I'm thinking that the soft-update-inconsistency error may have been
:just a red-herring due to a bad sector -- but the 'write error'
:is also occurring in the absence of bad sectors, and was already
:happening on DF-current as long ago as April 25.
:As an aside -- firefox pulled in and installed 37 other pkgsrc
:packages as dependencies with not one error, before starting to
:build firefox itself.  The only 'write error' I've seen is during
:the building of firefox.

    Ok, so try rebuilding just firefox (since now you have all the
    other dependancies installed) over and over again and see if you
    can consistently get the 'write error'.  

    I still think ktrace may be our best bet.  It sounds more like an
    application bug then a kernel bug.

    I will attempt to reproduce the problem.
