Blocking is perfectly fine. I'm wondering if I need things to be 
shared now or something? Not used to programming with threads. 
Adding a shared modifier recursively onto every piece of data 
that needs it is a ton of work though.

I don't want to copy the data around since it's many gigabytes, 
but I'm sure there won't be any data races; main thread will 
start 2 threads, one for running the timer and one running the 
function call. The main thread doesn't access the data until both 
the timer and function call threads have stopped completely.
