Calling external SHA1 will be too slow (it loops many times), but
maybe looping a elisp sha1 in the idle-timer could work (every loop is
short and it can be resumed fast).  Perhaps the simplest thing is to
disable hashcash in Gnus if the external "hashcash" binary isn't
installed, and to enable it if it is present, though.
