I looked into it, but didn't find a way to exit the Python interpreter and
come back in GDB by typing a Python command.  That command would somehow
have to fool the Python interpreter in thinking that its input stream, which
we pass here:

https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=blob;f=gdb/python/python.c;h=d6f7f99c457300cba8e6dbe590ac15b4b2e2b110;hb=HEAD#l302

has reached EOF.

I'm not saying it can't be done, just that I haven't found a way.
