### Call History
Each thread maintains a circular buffer of call history that is used to provide debug information in the event of an error. The buffer itself consists of an array of pointers-to-strings. Cyclone generates calls to runtime function `Cyc_st_add` as part of the compiled code to populate the buffer. This function must be fast as it is called all the time! So it does the bare minimum: update the pointer at the current buffer index and increment the index.
