[PATCH] poke: Handle `EINTR` as non-fatal error

[Mohammad-Reza Nabipoor]

2020-12-13  Mohammad-Reza Nabipoor  <m.nabipoor@yahoo.com>

        * poke/pk-mi.c: Add include `errno.h`.
        (mi_loop): Ignore `EINTR` when `select` fails. It's not a fatal error.
        * poke/pk-hserver.c (hserver_thread_worker): Likewise.
