also looks like there's some special initialization necessary for threads. I
doubt that this is handled by the new default behavior in 1.4.4. Don't know
that it's truly necessary if the network plugin is the only plugin using
gcrypt.

Here's a patch that works for me with 1.4.1.
I followed an example for pthread initialization and  initialized gcry to 32k,
only since that's apparently the default that's used in 1.4.3. I did it in
network.c's module_register function. Kind of an abuse, I know.
