[IronPython] Traceback line numbers in Mono (workaround)

[Sanghyeon Seo]

Hallo, alle Mono Nutzer, (or something like that)

One of the most annoying things in using IronPython on Mono is that
line numbers are missing in tracebacks.

There is a workaround now!
For full details see http://bugzilla.ximian.com/show_bug.cgi?id=80191

Summary:
mono --debug ipy.exe -X:SaveAssemblies script.py

This will display correct line numbers in traceback. You need both
--debug and -X:SaveAssemblies. The issue is that Mono can't display
line numbers from AssemblyBuilder built in memory, but only from
Assembly loaded from disk.
