[issue20703] RuntimeError caused by lazy imports in pdb

Serhiy Storchaka added the comment: Having a side effect at import time is not good. It will interfere with programs which just import pdb, but not use it. There are two other options: 1. Import readline at top level, but call set_completer_delims() lazily. 2. Do not import readline at all.
