I'd like to mention this is not the only case where GDB abandons something
when hitting something else. E.g. if you have solib events enabled, and do
next and solib is loaded, the "next" operation is aborted, and you're stuck
in the middle of nowhere with no chance for a frontend to do anything.

It would be nice of infrun be rewritten to use a proper state machine, permitting
nesting.
