The timing is of course problematic.  One approach could be to merge it
into 2.6.19-early, backport into 2.6.18.x after a few weeks.  I don't know
if that's a lot better, really - it's unlikely that anyone will be running
serious performance testing against 2.6.19-rc1 or -rc2.

I'm struggling to understand how serious this really is - if the bug is
"longstanding" then very few machines must be encountering it?
