Yes, that would be one way.  That actually reminds me of another issue
that I forgot to mention: glibc has a backtrace API that can be called
from user-code at any time, not just at faults.  At the moment we are
exporting something similar called cygwin_stackdump but we don't declare
it in any header.  Would it be worthwhile to try to match the glibc API
and export it under the same name/output format?
