Hmmm, I cannot verify it right now, but everything up to STRONG_RANDOM
should have been using /dev/urandom. Only the VERY_STRONG_RANDOM
in libgcrypt should use /dev/random, but this is not used for normal
TLS sessions.
If this is not the case then it's probably a bug either in libgcrypt
or in gnutls.
