            Bug ID: 18945
           Summary: gdbserver cannot be interrupted on linux when pgid
                    doesn't match pid
           Product: gdb
           Version: 7.10

patch

In gdbserver/linux-low.c, linux_request_interrupt uses kill(-pid, SIGINT) to
interrupt a process, but this fails when the attached process is a member of
another process group.

Is there any reason that sending the signal to the entire process group is
desired, or can we get away with changing it to kill just the single process?

Trivial patch attached
