That is my guess too.  There is code inside sit-for (or rather
wait_reading_process_output) to handle process output while waiting;
and I can verify that the code works, at least on GNU/Linux.  However,
if the sit-for runs busy idle timers, it is possible that process
output is not handled while those timer functions are running (unless
they call accept-process-output etc.)

It's in two packages (cedet and jdee) distributed outside of Emacs.
