[lldb-dev] Thread resumes with stale signal after executing InferiorCallMmap

I tried to repro it using standard LLDB client on a simple program that I could share. Well, the problem does not exactly repro as in my case - i.e. the signal is not re-delivered to the thread. But LLDB does get confused state: the program continues but at the same time lldb shows its prompt as if the program were stopped. I.e. the recovery from signal during expression evaluation is buggy. Sorry, I am not sure that I will have time to look into it deeper - it is not a blocker for me at this time.
