My main worry is with portability. Have a look at src/od-linux/exectasks.h. 
This stuff isn't portable - it's by definition architecture and compiler 
dependent. We'd need to provide similar stack magic support for other 
architectures (I'm not too worried about only building with GCC right now). I 
don't mind doing PPC and m68k versions myself, but I haven't a clue about 
SPARC, MIPS, ARM or any other architectures that people are using. ;-)

The stack magic stuff isn't used by the Unix versions of UAE currently. The 
gfxlib stuff isn't used, and neither is the uae_AllocMem() call.

I would certainly be interested in taking a look. I'm sure others would too.
