... and to wade in, here's an idea I'm toying with: every 1000 or so bangs that until sends out, check the CPU clock. Each time more than a second elapses, go check the input buffer from the GUI, and execute it (so that mouse clicks would appear within the context of the until loop!) This would allow you to delete the offending until, assuming you know where it is.
Another idea: have a GUI item that interrupts Pd, causing the stack frame to be rudely dropped and all clocks to be unset. aren'y they both ugly? but maybe something like this is needed ...
