> Multi-target debugging support

This is great! I really needed this multiple times over the years. Always wanted to compare some data between 2 executions of the same applications with 2 different inputs or 2 revisions of an application. This should really help with triangulation of regressions etc. automatically using a single script within gdb!

GDB has had that in the form of Multi-process debugging for a while. Multi-target I believe extends this different remote stubs and architectures, such as debugging both an x86 and x86-64 process. Besides that I agree it's really useful on the occasions that you need it to hunt down some non-determinism or what not.
