This function should not be returning 0 with a valid string, and is a simple
wrapper around the lower-level runtime function.
I /think/ that the problem is that NSSelectorFromString() wraps
GSSelectorFromName() (for irrelevant legacy reasons - this indirection can
probably be deleted now), which calls sel_getUid(), not sel_registerName().
The former function returns 0 when the selector is not already in the selector
table. The latter always returns a valid selector.
I believe that the correct fix is modifying NSSelectorFromString() to use
sel_registerName() and replace all other references to GSSelectorFromName()
with sel_registerName. The not-quite-so-correct fix is to modify
GSSelectorFromName() to call sel_registerName().
