Don't bother. Cocoa is quite explicitly designed to not support event
processing on any thread other than the main thread. No amount of
"trying to isolate" Cocoa functionality into a thread will make it work.
Because I have no access to the main thread.
The only way you can't have access to the main thread is if you are
using a piece of software for which you have either no source or don't
have the ability -- the rights, most typically -- to modify said source.
If you have the source, modify it so that whatever it is that is
consuming the main thread is no longer on the main thread.
You'll need to give some more information on exactly what it is you
are trying to do -- what you are trying to integrate with -- to gain
more help.
I am still suprising of a such limiation of Cocoa on MacOSX while it
works
perfectly with GNUstep.
Think it through; why would Apple or NeXT waste engineering resources
making this work? Making anything thread safe -- especially complex
things -- is extremely difficult and there is always a performance hit
for doing so. Always.
And doing so offers what feature or advantage to the developer?
Event processing is an inherently linear process. You generally
cannot respond to the next event until the current event is fully
processed. Efficiency is generally obtained by coalescing related
events -- sequences of key events while typing -- or by ignoring
events like mouse moves when they aren't relevant.
