The signal mask is inherited by children, so if we don't remove it
the shell module spawns processes which are accidentally resistant
to most signals.
see: man sigprocmask (znc uses pthread_sigmask, but they act the same)
bits are being set in file mode rather than open flags. As a result file permissions get strange bits set.
