theraven 19e71aa612 __weak is only allowed on ivars and globals, so we need to turn the Observation structure into a class. 
Richard:

I've run the test suite with GC disabled on Linux/x86-64 and nothing broke, but can you please review these changes carefully anyway?

We seem to be using a complex custom allocator for a structure that is not allocated or deallocated.  In typical programs, it looks like we're actually just wasting memory by using the memory pool here.  Looking at the commit log, this hasn't really been touched for about 10 years, so possibly the assumptions are no longer valid.  I can only see this being useful if someone is adding and removing hundreds of notification observers every run loop iteration.  Do you have code that does this?  If not, then can I remove the custom allocator?
