Expensive plugins

[Gordon Tyler]

Somewhat related to this, I was wondering why bzr explorer launches
subprocesses for qbzr commands? Surely it would perform better and avoid
command-line encoding issues if qbzr commands were invoked in-process?
It would also avoid the weirdness on Mac where each qbzr command
currently running appears as a separate icon in the Dock, in addition to
the icon for bzr explorer itself.
