Commit 59f2ba44 changed the devel docs to tell that on Linux, just running the gdb command `continue` is enough to restart the plug-in process. Maybe it is true on some specific setups, so I leave this part of the note, but for sure it never worked for me. I may run `continue` as many times as I want, the process stays stopped until I explicitly send a SIGCONT signal (our code raises itself a SIGSTOP which requires a SIGCONT for continuation of the process). Maybe in some configurations, gdb actually sends a SIGCONT when `continue` is run but not in others? No idea. Anyway I add back the part about sending a SIGCONT too, then people can test and choose which procedure works for them.
