Completely unrelated to your questions, but cyg_thread_delay(1) reminds
me of something I always wanted to ask:

How long does cyg_thread_delay(1) wait, assuming a 10ms tick? 0-10ms or
10-20ms?

If it's 0-10ms, then it's pretty dangerous to use, because you usually
mean[1] "some short delay in the order of a few ms", but you could just
as well get no delay at all, if the next timer interrupt happens to
arrive right after the call to cyg_thread_delay().
