-------------------------+-------------------------------------------------
Resizing the terminal window while pdb is active in an HTTP handler thread
using `--noreload` on linux causes the kernel to raise an error condition
that crashes django (true for current HEAD `8f50ff5b` and e.g. 1.6). To
reproduce this:
1. Put a `pdb.set_trace()` call in a view function.
2. On linux, start the server with `--noreload`.
3. Send a request to the URL. The `pdb` prompt should now be in effect in
the terminal.
4. Resize the terminal window. This will cause django to crash with
`select.error: (4, 'Interrupted system call')` as in the traceback below.
The bug only affects `--noreload`. It does not occur with `--noreload
--nothreading`.
