and doesn't close them before execing gpg? That is a real bug in
duplicity and we should better not work around it but only detect it.
For Libgcrypt however, we can't limit the number of used file

rndlinux is a misnomer these days because it is actually an access
module for /dev/random style devices as available on all kind of
platforms. I am not sure whether whether poll is availabale on all
these platforms. You should add a test for a working poll or use poll
only for linux (to simplify the configure test).
Die Gedanken sind frei. Ausnahmen regelt ein Bundesgesetz.
