No, this is not true if you are in a truly multithreading environment.

I agree,  in multithreading/multiprocessing environments,  the GNUstep
library is not clean, and the return([[target retain]autorelease]); is
one step toward a more correct solution.

I don't really agree (maybe because I am coming from Irix/SGI where multithreading is an important, daily issue and not just a hypothetical case as in other environments...), either a solution is/has to be 100% threadsafe or it is clearly stated as not and then it is up to the developer using GNUstep to make it threadsafe. This retain/autorelease 'solution' is definitly not threadsafe, so why make the effort at all? You cannot have a 90% threadsafety and it would be very dangerous to address the problem using such an philosophy.

...but maybe I misunderstand your point here?
