* agent/gpg-agent.c (agent_libgcrypt_progress_cb): Sleep for 100ms on "need_entropy". -- During key generation Libgrypt will read from /dev/random which may block. Libgcrypt is not nPth aware and thus the entire process will block. Fortunately there is also a select with a short timeout to run the progress callback. We detect this in gpg-agent and introduce a short delay to give other threads (i.e. connections) an opportunity to run. This alone is not sufficient, an updated Libgpg-error is also required to make the lock functions nPth aware. Signed-off-by: Werner Koch <wk@gnupg.org>
