I definitely blew the need_resched stuff.
I found it. I was clearing the 'astpending' variable in doreti, which
used to be just fine, but now that we have two flags in it instead of
one it was clearing the need-resched flag bit as well as the astpending
flag bit.
If you don't want to wait, here it is (it's really the last bit that
fixes the problem. The first two bits are incidental).
I've committed the fix. I would appreciate others testing it as well.
It seems to solve the problem I was able to reproduce on my systems.
