I think the Trace and Debug facilities you want can be easily supported
with and environment variable: the code will look it up and set the
filestream where the output should go:

export MONO_TRACE=debug,trace=/dev/null

would mean that debug is enabled (and the output goes to stderr) and
trace is enabled and the output goes to the file named /dev/null.
If either debug or trace is not mentioned in the var or if it's not set,
you get no output. This is a runtime library issue, so there should be
no switches for it in mono/mint.
Anyone that wants to submit a patch to implement this?

That said, I don't think the Debug and Trace classes should be used in
the libraries (certainly not in corlib).
