realtime Ruby GC

I work with PureData, a realtime audio/video application, and I made a
Ruby scripting plugin for it, but currently it somewhat sucks because the
GC introduces latencies that you don't find at all in the Python scripting
plugin, for instance. I've had reports of people getting clicky sounds in
the audio because Ruby couldn't do a job in the required amount of
milliseconds, because of the GC (Normally I do video and in that case the
problem is much less noticeable).

So I would like to know whether there are patches to the current stable
Ruby (1.8.1) to make the garbage collector faster, or any other patch that
could be ported to 1.8.1.
