//the pepper api is flawed. deeply flawed.
//1: api calls (including various gl calls) may only be made on the main thread).
//2: the main thread may not use non-asyncronous calls.
//the recommendation to get around this is to run everything on a worker thread, but to make calls to the main thread to do the actual call, then signal the worker thread to wake up again in the main thread's callback.
//which is impractical when you have 80+ different sorts of performance-dependant gl calls.
//I can't easily put things requiring file access on another thread, if only because it would make alias/exec console commands non-synchronous
//to get around this, I instead make my own memory-only 'filesystem', populating it at startup with downloads. I *really* hope your browser/server are set to enable file caching.
//at some point I'll periodically write the data back to a persistant store/reload it at startup so saved games/configs can work
