[Mono-osx] OS X builds and -DUSE-MUNMAP

[Eoin Norris]

Does the absence of this flag mean that abolutely no memory will ever  
be released. I can see my application increasing in size - mostly the  
mono layers  which has the business logic - without seeming to give  
anything back up.  The cocoa layers do ( I can see memory being  
released when UIs elements are removed).

Is this true even if we call the garbage collector directly in mono -  
GC.Collect et al?
