b31b545032 malloc'ed all state instead of having a gigantic struct 
state_t is now 208 bytes on x86_64 instead of 26 MB. Startup is a little slower though because of ~7000 malloc calls.

c4f7cfb449 The state pointer is no longer global, but passed down to every function. 
...and surprisingly, it's not any slower. if anything, it's 1% faster.
