-/* If the user has switched threads, and there is a breakpoint
-   at the old thread's pc location, then switch to that thread
-   and return TRUE, else return FALSE and don't do a thread
-   switch (or rather, don't seem to have done a thread switch).
-
-   Ptrace-based gdb will always return FALSE to the thread-switch
-   query, and thus also to PREPARE_TO_PROCEED.
-
-   The important thing is whether there is a BPT instruction,
-   not how many user breakpoints there are.  So we have to worry
-   about things like these:
-
-   o  Non-bp stop -- NO
-
-   o  User hits bp, no switch -- NO
-
-   o  User hits bp, switches threads -- YES
-
-   o  User hits bp, deletes bp, switches threads -- NO
-
-   o  User hits bp, deletes one of two or more bps
-   at that PC, user switches threads -- YES
-
-   o  Plus, since we're buffering events, the user may have hit a
-   breakpoint, deleted the breakpoint and then gotten another
-   hit on that same breakpoint on another thread which
-   actually hit before the delete. (FIXME in breakpoint.c
-   so that "dead" breakpoints are ignored?) -- NO
-
-   For these reasons, we have to violate information hiding and
-   call "breakpoint_here_p".  If core gdb thinks there is a bpt
-   here, that's what counts, as core gdb is the one which is
-   putting the BPT instruction in and taking it out.
-
-   Note that this implementation is potentially redundant now that
-   default_prepare_to_proceed() has been added.
-
-   FIXME This may not support switching threads after Ctrl-C
-   correctly. The default implementation does support this. */
