explicitly asked for. I think we should really display a warning in that
case.
It's fine with me either way; it's just that `stackwarn.patch` made me
think you intended to make any memory warnings only show up with `DEBUGMEM
> 0`.

That is clear; it is more of an aesthetic issue, so to say.

you use 1G). If you have a machine with lots of RAM, you may want to
actually use it.
Sure, the amount in my branch was just meant to be some arbitrary default
until I found a better solution (which I never got around to). I thought
about making this configurable, with some reasonable default that would be
sufficient for most users.
