            Bug ID: 15853
           Summary: 'thread apply all inetrrupt&'  shows inefficiency on
                    remote targets
           Product: gdb
           Version: unknown
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: mbilal at codesourcery dot com

In the case of 'interrupt -a&' command gdb sends only one packet to 
stop all  threads as $vCont;t#b9...

But in case of 'thread apply all interrupt&' GDB issues indiviual packets for
each thread.I think that In non-stop mode 
'interrupt -a&' and 'thread apply all interrupt&' commands all equals but time 
efficiency of later command is less.

Also.

If user issues a command like 'thread apply all interrupt -a&'
GDB accepts it and GDB will stop all threads on first vcount;t packets  but due
to loops, it sends vcount;t packet for all remaining threads altought gdb has
already stop all thread so IMO it is a bug.
