What code in QEMU is actually still using threads ? There used to be a Xen
specific patch to the IDE layer to perform DMA ops in threads, but that was
removed when xen-unstable synced with QEMU 0.9.0. Not aware of anything
else using threads in the QEMU device model - its pretty dangerous because
QEMU's internal data structures basically all assume single-threaded access.

Dan.
