On x86, pressing the scrolllock button may effectively prevent procd from
rebooting
the system. This happens because procd tries to write to /dev/console, which in
that
situation is blocked, effectively blocking procd from rebooting the system.
This patch puts procd's stderr access into non-blocking, which will prevent the
boot from being stuck.
