>Description:
        I have a full pkgsrc bulk build going on my Kurobox/PRO, which
        has 128MB memory and 512MB swap configured.

        Attempting to build databases/mysql51-server causes the
        machine to hang hard, so that it requires a power cycle to
        recover.  It has otherwise been fairly well-behaved
        stability-wise since the bulk build was started.

        I have DDB enabled, and ddb.fromconsole=1, but when
        it wedges, I am unsuccessful in breaking out to DDB.

        The version I tried to build was 5.1.65, from early in
        pkgsrc-2012Q4's cycle.

        By the looks of what remains on disk after a reset, it appears
        that it wedges somewhere in the configure phase(!?)

>How-To-Repeat:
        Try to build databases/mysql51-server; watch it wedge.
>Fix:
        Sorry, don't know.
