In most cases of stoppage the swap use is low, 50 MB or sometimes less.
Up to about 6-700MB the machines slow their progress, but keep going and
there are no complaints on the console about swap taking too long or
insufficient. If there's a connection to swap use, it isn't obvious.

It seems to be related more to hours of runtime than swap use. 

More to the point of my question, if the machine is swap-bound,
shouldn't the debugger escape still work?

Thanks for writing,
