Comment (by bgamari):

 > PS: Is there any way to make the "out of memory" error a little bit more
 informative? Something that informs the user of how much memory was
 already being used and how much more was going to be reserved when the
 failure was seen?

 Probably; unfortunately there are a number of places where this error is
 thrown scattered about the runtime. This should also be fixed.
