Presumably you are talking about off-loading some of the work to some
sort of stub running in the process.
Could you LD_PRELOAD something that communicates with its controlling
GDB via a named-pipe/UNIX domain socket? When an event of interest
occurs, the stub would notify GDB, which would then attach to the process.
