PKCS#11 "Application and processes" instructs the sequence 

that should be taken after fork().
Applications should call C_Initialize() immediately after fork()
to reinitialize the provider.

The change monitor the pid that calls C_Initialize(), if it is
different than previous C_Finalize() is called.
