Currently BMC (block memory instruction) is not a subject of timer interrupts, so it can block program execution for quite long time.

Solutions:

Turn it into iterator and save state of block memory copy
- Issue: Executor would have to check for it each time even
  I believe this instruction is pretty rare
Remove it.
- It is causing timing issues
- We are still copying to intermediate buffer, register array can serve as it too
  - Issue: Having to reserve registers / save+restore
Limit it to some sensible size (max 255 bytes at time? max one small page at time?)
