New submission from Hernot <christoph at out-world.com>:
I like the PDB debugger it is a quite powerfull tool, despite a few donws. One is that cleanup code eg registered by debugged script, module is not executed on restart. a crude hack is to check whether pdb is invoked via python -mpdb using inspect and decorate pdb._runscript and psb._runmodule methods with own versions calling registered cleanup methods before returning to main.
A cleaner approach would be if either pdb intercepts atexit calls recording any method which is registered by a call to atexit.register or provide it's own atexit method to register methods which pdb should call to revert to a clean enviroment expected by the script or module at startup.
open to any discussion, examples will follow as necessary.
