After some QEMU patching I'm able to confirm this.
QEMU hangs a lot on my Darwin/ppc64 host though, not just here. My  
Haiku/i386 guest keeps hanging for multiple seconds.

It appears there's some QEMU regression, introduced within the last  
four weeks. Any help bisecting/fixing would be appreciated.
