Seems that arch/um/kernel/sigio_user.c:write_sigio_thread begins its poll before there are any fds in current_poll, so update_thread caused by a add_sigio_fd shortly thereafter hangs while waiting for a response. A sleep(1) at the beginning of write_sigio_thread "fixes" this :-) - Werner -- _________________________________________________________________________ / Werner Almesberger, Buenos Aires, Argentina [EMAIL PROTECTED] / /_http://www.almesberger.net/____________________________________________/ ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
