[IPython-dev] IPython In-process kernel support

There is no real obstacle, but it isn't very convenient. The trouble is
that the terminal frontend is truly synchronous, unlike a GUI frontend
which is driven by an event loop. Here is how the terminal frontend
executes code:


You can see that 'handle_stdin_request' will never be called. To handle
stdin, something must be special cased: the terminal frontend, the embedded
kernel, or the embedded kernel manager. I'm not sure how to handle this
cleanly. Perhaps the simplest thing is to add a switch to the kernel for
calling 'raw_input' directly (bypassing the kernel manager). Only terminal
frontends would use this switch. Perhaps others have better ideas.
