[Xen-devel] [PATCH][XEND] Fix yet another information-destroying backtrace in Xend

[Hollis Blanchard <hollisb@xxxxxxxxxx>]

Every time you call traceback.print_exc() from an exception handler, you
throw away all the traceback information you've accumulated to get to
that spot. I'm not going to do a global find/replace without testing,
but I know the below patch works and is needed.


Fix yet another information-destroying backtrace in Xend.
