I just observed the problem on sage.math. (64-bit amd linux).
It doesn't happen on OS X. The code's identical, so I guess
things like killpg work better on OS X... In any case, I consider
this a very serious bug, and *will* add extra code to deal with it
better on Linux 64-bit.
I've posted this to trac.
