They seem to give some hints. Your trace shows the process-ids, no timestamps
and Don's doesn't show process-ids. But stripping away that column, I can see
that his process is (I'm guessing) running on a network connection while yours
is local machine (that's guessing by looking at some of the calls they make).
His is getting occasional EAGAIN errno's reading from the pty (perhaps because
it's slower). I don't see any detail from the subprocess on his - perhaps it
doesn't use the -f option of strace. Anyway, it seems that the failure is
on the child process, since I don't see a call on the parent side that fails.
