The short answer is that you can't increase the max timeout.
The long answer is that you can work around it:
- If you're doing a lot of computation in your FlasCC code
- You could break up your execution into smaller "chunks" that get called asynchronously.
- You could use pthreads within your FlasCC C code (FP 11.5+)
- You could put your FlasCC instance into a Worker thread (FP 11.4+)
