    works with 64 bit python

    If this is the case, then under what config doesn't it work. I assume it doesn't work in 32bit python.

    Right it does not work in 32bit python on Centos 7. I will try it on Ubuntu tonight.

    Same behavior on Ubuntu. Using a debugger (pdb i assume) via ipython works correctly.

    I get the same issue on Debian 32 bit. When I run strace on the Python process, it's waiting on a futex.

    $ strace -p 3906
strace: Process 3906 attached
futex(0xc5df40, FUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME, 1, NULL, 0xffffffff

    johns (@jhsterling) Please could you confirm you're using Ubuntu 32bit.
    I'd like to confirm that everyone having this issue is using a 32bit Linux OS.

    Closing as the experimental debugger resolves this issue and the experimental debugger is the default.
