[issue30006] Deadlocks in `concurrent.futures.ProcessPoolExecutor`

New submission from Thomas Moreau: The design of ProcessPoolExecutor contains some possible race conditions that may freeze the interpreter due to deadlocks. This is notably the case with pickling and unpickling errors for a submitted job and returned results. This makes it hard to reuse a

[issue29533] urllib2 works slowly with proxy on windows

Marc Schlaich added the comment: This could be even a security issue. People might rely on a proxy as a privacy feature. In this case the proxy should do forward/reverse DNS requests and not the client. Doing DNS lookups to check for proxy bypass doesn't seem right. I don't think that major

New submission from Mike Gilbert: Some effort was made to port Python to OpenSSL 1.1.0 (see issue 26470). However, the code still uses several deprecated functions, and fails to compile against OpenSSL 1.1.0 if these functions are disabled. This may be replicated by building OpenSSL with
