This is where it gets a bit weird... It seems there are multiple
custom remote debug implementations.

From some discussion on what PyCharm does (how it was broken by a
company firewall) it looks like it starts an ssh connection to the
target machine and runs pdb. PyDev may do something similar but it
looks like it replaces pdb with its own module.

Microsoft uses https://github.com/Microsoft/ptvsd. Visual Studio Code
is actually quite good and should run on Gentoo - it is open source,
as is their remote python debugger. I had forgotten about it but if
you want a GUI do strongly consider it.
