As documented, curl_global_init may not be called from a thread but from the
main function before any threads are running. Ideally, you would be able to
hook into an initialization function of some sort that's called before the app
server starts your thread. Failing that, perhaps you can play some games with
the dynamic loader and use __attribute__ ((constructor)) (or the non-gcc
equivalent) to force your initialization function and curl_global_init to run
before the app server even starts.
