It's also not a very accurate representation of the amount of memory
that's actually being used.  If you're looking at the VSIZE column,
well, it's a lie. :)  And while the RSS column is closer, it still
doesn't take into account memory that's shared between processes,
which Mono apps use quite a bit.

A tool like exmap or smap will give you a lot more accurate numbers of
memory usage.  ps or top are only good for very basic diagnostics,
like if you have a (single instance of an) app using a ton of memory.

I'm not denying that there's a bug here -- certainly why you have 14
instances of it running is puzzling -- but memory usage is often
misunderstood on Linux.
