Some bad quality BT-headsets block bluez socket sometimes for hundreds
of milliseconds, especially when changing mode. When the module tries
catch up the lost time it may SBC encode up to half a second of audio
without yielding. On slow machine this may cause maximum RT time slice
to be exceeded. Cleaned out the minor fix that slipped into first version
of the patch.
This has the benefit that we can properly support ALSA devices where
only the raw 'hw' device exists but no 'front' although it's a proper
2ch stereo device.

No problem, I was mainly looking for a hint that to your knowledge there
should be no wierd side-effects from stubbing out the reserve and dbus
functions inside reserve_wrapper. Thanks for said hint. ;-)
Attached is a patch to include "reserve_wrapper.[ch]" in the non-dbus
builds, and do said stubbing when HAVE_DBUS is not defined. It has
passed moderate testing: built both versions, both pass
"pulseaudio --dump-modules" with no weird messages, and the
"--disable-dbus" build works and produces audio as expected in some
simple tests including RTP.

Well, you also broke the solaris module between 0.9.15-test8 and 0.9.15.
Have you considered release candidates?
Patch follows. It would be nice if API changes could be made without
breaking things when the effort to avoid that is trivial.
