Max, I'm on your side, really :) Silent failures are a big problem and should not be allowed to persist. What I don't know is whether the remedy for low space is simply to log it and then proceed to crash, or if a handler can do something useful. The handler probably would need to be registered; otherwise, the low space condition might show up in a thread other than the one hogging all of the memory, I think.
If a handler had to bail me out, I would probably want that logged, but if it is my handler, I should be able to do the logging.

But then again, if there is a low space watcher anyway, shouldn't there be a way to register as a listener or something? Igor, I haven't run your code yet but it looks exactly like what I was looking for! Thanks.
