If the bar is that high for patches on the release branch, then
this change does not meet it.  We'll still need to address this on
the trunk.

Fear not, it's already patched in the Apple GDB branch. :-)  

My concern is for (a) environments where pointers to undefined
structures are used, and (b) lookups of undefined symbols.  Obviously
it's not a great travisty if (b) is slow, but (a) will hit anyone
who has libraries that try to hide the implementation from the
interface in the same way that the Appple Carbon libraries do.

I probably won't have time until next weekend, but I'll be sending
modified versions of the profiling and symtab patches to incorporate
many of the suggestions on the list.
