What about making --enable-io-thread default as an intermediate step? That would leave --disable-io-thread as temporary workaround until all issues are fixed. The latter could generate a big fat warning that this
mode will be removed before 1.0.

Yes please, that proposal sounds much better.

If http://wiki.qemu.org/Planning/1.0 is still up-to-date, we have about
six weeks to make I/O thread work everywhere.

I'm not a big fan of just flipping the configure flag. There is other work being held up by disable-io-thread like the timer conversion.

If there aren't known issues, then I want to remove the non-I/O thread code. git history is still there for anyone that wants to test w/o it.

My problem is that at HEAD *none* of the i386,ppc,sparc guests that used to work about a month ago boot *at all* on my Darwin/ppc64 host.

Might be TCG, might be the new MemoryRegion API, might be (non-)I/O thread. Means a lot of git history testing despite little time. An ultimatum to make things even worse doesn't really help there... ;)
