For processing events, RGtk2 has moved away from using the old tcl_do hack
and now synchronizes on the Windows event loop. In Rgui.exe this works fine
(well mostly), but in Rterm.exe, users report the following warning from
GLib: "main loop already active in another thread". The most obvious way
this could occur is if the Windows event loop were iterating in multiple
threads. This does not seem to be the case from my casual inspection of the
R source.

Any help is appreciated.

Thanks,
Michael
