This looks really useful.

Nice trick. We should comment the others too.

I am a little confused by this. Where do those suppressions appear and how/when
would you use them?

Aha. Yes, those testcases change uid during their runtime and so they no longer
own that file.
That seems OK. We aren't really testing the gdbserver functionality here.
Also these test must be run with privilege.
BTW. setfsgid04 doesn't seem to exist, did you mean setfsgid03?
