Sorry, my fault!

Niko (the packager whose rpm i picked up ) told me that, i wanted to just to probe new features
so basically i ignored the docs....(like a good newbie  :-)  )

IMHO this is not very elegant as the purity of process isolation is gone. 

Was performance the key on introducing such a complex driver? im very new
to just make this judgement but for the whole thing (minus opengl and the like)
it seems enough a stdin/pipe interface than making a big driver.

Perhaps memory conservation is another issue (well is erlang VM better at managing 
memory than a full blow C++ aplication??? ). 

Just checking
http://apps.sourceforge.net/mediawiki/wxerlang/index.php?title=Memory_management

shows a bif efort to catch deleted objects and try to be in sync with the pure erlang side...


its not criticism, but mere curiosity, design questions are very educative.

Regards, Angel

PS: Ive just found http://wxerlang.sourceforge.net/docs/Report.pdf seems very promising for insigths..!
