We need a bit more context to know where you are trying to put this
code. I tried to type it in a "pypy-c" executable -- is that what you
have in mind?
In "pypy-c" I can interrupt the infinite loop with Ctrl-C, which is what
I expected. (To get this result you may need a "pypy-c" translated with
the '--allworkingmodules' option, otherwise I'm not sure signal handling
If you mean that you tried to put an infinite loop in an RPython
function and translate that, then no chance. The translation toolchain
is not really good with strange inputs: it only does something sane if
the input is sane (which means, an RPython that actually works and was
reasonably well tested first).
