I'm seeing this error code when I reinitialize after a fork and use
soft-tokens like softhsm under p11-kit.  Run for example the attached
test (has to be compiled as a p11-kit test) and you'll see:
p11-kit: (unknown): module failed to initialize: The module has already
been initialized

Also printing in stderr when not being instructed to is quite dangerous
for a library. In that particular case that error was going out to
apache log. Maybe all errors should be silenced unless the P11_KIT env
variable is set or so.
