No, we just synchronize our internal state. Calling C_Initialize on in
pthread_atfork() is pretty wild. Most uses of fork() are fork/exec.
Besides not being async-signal-safe, many C_Initialize's are large
blocking pieces of code.

Anyway ... we expect the caller to C_Initialize after fork as they would
when using a PKCS#11 module without p11-kit. I know this doesn't solve
anything for gnutls, but it's not a trivial problem.

Cheers,
