I'm not really sure if we're speaking about the same thing then.  Erlang is
best utilized as a stateless platform, with a "fail early fail often"
philosophy, and crashing the entire interpreter in the event of some
underlying problem with the OS fits that entirely.  You seem to be seeking a
platform that lets you program defensively, handling errors rather than
crashing and restoring with a clean state.  In that regard, Erlang may not
be the best language for you to work with, but then again the problem of
successfully recovering from an out-of-resource condition is an extremely
difficult one to handle well without scrapping it all and trying to restart
with a clean state.

I'm not really sure what alternative behavior you're proposing, either?
