All we really need is something that can handle patterns including ".*",
because that's all that is used in the patterns in "resultmap".  That
should be doable (inefficiently, but who cares) in just a few lines of
code.  I'll go for Plan B for the moment.

Yeah, I thought the same --- you need it on a platform that won't
let you run dozens of processes under one userid.
Will take care of it.
