Wow, well hopefully the fix gets integrated soon enough to reflash,
especially if a workaround it too odd/slow (code wise). I haven't been
following the code closely lately, my mind has been in a space of
learning logic to apply numeric solvers to constraints problems. Very
mathy and different-to-me stuff. It is going well though... I will try
to take a look at what you are doing in more detail this weekend.

Can you do this with some blocking loops instead of ISRs? (my ignorant
of the details, quick response) Something like:
for pulse in range(num_pulses_requested):
    pin1.toggle()
    delay(pulse_width)
    pin1.toggle()
    # maybe add some NOPs here to account for the JMP that will happen
at the end of the loop
    delay(delay_between_pulses)
    pin2.toggle()
    delay(pulse_width)
    pin2.toggle()
    delay(delay_between_pulses)

I'll study your code sometime this weekend and try to give a more
informed response :)
