In a case like this you could perhaps take the RT-Linux approach, which
runs Linux as a low-priority task in a RTOS. The high priority
things can be device drivers, special interrupt handlers, etc. It should
probably be possible to do something similar with Python as a low priority
task on a RTOS. In fact one could just install Python on an RT-Linux
system and you'd have it. The fast stuff would need to be coded in C
or assembler, but it's unlikely to need dynamic memory allocation. Having
Linux available might allow you to place a bound on the memory used by
Python, assuming you wanted to do that.
