Summary 0003297: island export and nameMap tables filling up
Description The export and nameMap tables of TIsland always grow and never get smaller, effectively causing a memory leak.

Some of the subissues that cause this are triggered by any mouse movement at all, or by selecting. So, for example, if there is a window or other selectable object near the edge of the morph, you can move your mouse over the object to highlight it and then slide your mouse directly off the morph, and the tables will just grow and grow forever without anyone having any interaction with the system at all.
Additional Information There are several reasons for this, which I'll report as child issues.

This is the reason for Zamp's observation about nameMap in 3252, but might not be the reason for the major effect that 3252 is all about (system eventually freezing up).

I marked this as severity/priority = block/high as an overall issue because memory leaks are bad, but the subissues can be dealt with individually. (E.g., we can fix offending code without changing the compiler, and thus close this overall issue, leaving the compiler issue open for a while.)

 The attached .cs collects the quick fixes for all the subissues. That is, we don't exhibit the problem reported here if you have this .cs loaded.

 Nice work and thanks for providing the change set. I've integrated it but I'll leave the bug open until such a time that we've fixed the problem for real.
