Daniel recently posted a list of X extensions supported by the Apple
X11 server. The MIT-SHM extension was part of this list but today I
found that at least in darwinports gtk2 is compiled with the
--disable-shm configure option. Does anyone know if fink does this as
well? Is there a particular reason to disable the use of the XShm
extension on OS X? This would explain at least some of the slowness
that people reported here lately.
