[Cocoa-sharp] Performance of UI

[David Jehring]

Thanks Edward, it is reassuring to hear that it is a known issue but
somewhat disappointing that such a fundamental problem has existed for so
long with no sign of it being addressed. Following the initial deafeningly
silent response to my post I have abandoned cocoa-sharp and gone back to the
somewhat more laborious task of porting my clients to pure obj-c. It seems a
shame but I cannot risk the issue not being resolved and ending up with
unusable applications.
