In which case, there is nothing much lldb-mi can do but to try to avoid this scenario. As I told earlier, ???select??? based solution increases time to run test many times. So that does not seem reasonable. I am OK with ioctl based solution and will commit it later if there are no more comments/suggestion.

Thank you for checking which solution is better for Linux.  Looking forward to
the ioctl commit then :).  Perhaps you could add some of this discussion to the
comment in CMICmnStreamStdinLinux::InputAvailable for posterity?

For those of us that have no clue on how to work with XCode projects,
tweaking just the cmake and gnu makefiles can break those builds.  Lldb-mi
wasn't being built in XCode last I checked, but I expect it will be some say.

As for this part, I agree it is a bit of a mess right now, but as Ilia points
out, it is not as simple as it sounds.  We should at least rename the classes
and files though.  Ok to replace Linux with POSIX in the files and classes?

Thanks,
