I realise now that this "nice" solution won't work, as the standard
library code says:

import socketserver

so modifying sys.path will just change the value of
sys.modules["socketserver"].  However, the vendored code instead loads
this module to sys.modules["_pydev_imps._pydev_SocketServer"] or
something like that, deliberately avoiding interfering with
sys.modules["socketserver"].

Ho hum.
