I have grumbled about the evilness of "current_base" before, and this just
proves the point: If two threads call event_init() at the same time,
they will both stomp on the same memory via current_base, and in all
likelyhood, neither of them will manage to get the job done properly.

Instead work on a local variable and don't assign to current_base
until the setup is complete.
