Rely on servers to implement timeouts, so that very short values (including 0) don't make mach_msg return before valid replies can be received. The purpose of this scheme is to guarantee a full client-server round-trip, whatever the timeout value. This change depends on the new io_select_timeout RPC being implemented by servers. * hurd/Makefile (user-interfaces): Add io_reply and io_request. * hurd/hurdselect.c: Include <sys/time.h>, <hurd/io_request.h> and <limits.h>. (_hurd_select): Replace the call to __io_select with either __io_select_request or __io_select_timeout_request, depending on the timeout. Count the number of ready descriptors (replies for which at least one type bit is set). Implement the timeout locally when there is no file descriptor.
