But more generally, why should Erlang crash when it gets low on memory?

Does the Erlang runtime not check for a malloc() or 'new' call returning NULL?  If so, that seems kind of crazy.

Or if the Erlang runtime *does* know when a memory allocation fails, wouldn't it make more sense for it to force garbage collection to occur and try again, rather than simply crashing?
