--- Comment #9 from Thomas Klausner <tk@???> ---
Can you please give more details what the thread interaction is?

If the threads are independent, then every thread makes its own file.

If one thread creates the JIT code and another one executes it, then split off
the mmaps into separate threads (but make sure that the W mapping is gone by
the time the X mapping is needed).
