Interrupting memray attach with Ctrl-C segfaults the application it's attached to

[godlygeek]

Run an application like python -m http.server & then attach to it with memray attach -v $!. The attach call hangs, because it's waiting for an allocation in the HTTP server process which will never come (unless you send it an HTTP request). But, if you Ctrl-C the memray attach call, the HTTP server process dies with a segfault, in at least some cases (I'm having trouble reproducing this, but it reproduced for @gusmonod consistently).
