pythonGH-157662) Send a real SIGINT to the main thread of the user process instead of calling _thread.interrupt_main(), which only sets a flag checked between bytecodes. The signal is sent while holding a new lock which protects sending a message, so that the main thread is not interrupted in the middle of a message. An interrupted wait for a response now releases its lock, so that the socket thread does not deadlock. (cherry picked from commit 9232c21) Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>

Send a real SIGINT to the main thread of the user process instead of
calling _thread.interrupt_main(), which only sets a flag checked
between bytecodes. The signal is sent while holding a new lock which
protects sending a message, so that the main thread is not interrupted
in the middle of a message. An interrupted wait for a response now
releases its lock, so that the socket thread does not deadlock.
