Sorry for not voicing anything for some time, but I am heads over 
busy with studies which started again, and some other things, and can 
only spend a little bit of time on Basilisk :(

Yes, it works well for me. Make sure that in the "Compiler Settings", 
you set the optimization level to "Default", then it will take the 
values from the build style.

Well, I haven't measured the boot time, but if I compare 
responsiveness, redraw speed etc. of the emulated machine between 
Basilisk 0.9 / OS X and the X-Window version, the X-Win version 
clearly wins.

yes, shared memory done in SysV style is not really supported, and 
according to Apple sources will not be in the foreseeable future, if 
ever. This also causes a problem with MIT-Shm in X-Window.
