Comment:

 Correct - heap overflow doesn't currently generate an exception.  It's
 something we should really do, but it isn't completely clear how to do it.
 For example, in order to run the exception handler, you need some heap
 space.  So perhaps you want a "soft" and a "hard" limit on heap space, and
 to get an exception when the "soft" limit is reached.

 Another question is: which thread(s) should get the exception?
