Re: Hideously slow VC status queries fixed

    parsing time could be an issue -- has anyone profiled 26,499 regexp
    matches lately ?

The speed of regexp matching depends greatly on the regexp itself.
If that regexp is slow, perhaps there is a much faster way
to parse that data.

Just turning off undo during the initial creation of that buffer's
contents will also speed it up somewhat, but I don't know if that is
significant.
