Cannot restart program after post-mortem

[dexter2206]

It seems to be impossible to restart the program after the post-mortem debugging. In original pdb, one can restart the execution by running restart (or run or any stepping command afaik). Performing the same action causes pdb+ to quit if run in post-mortem.

Steps to reproduce:

1. Create a short program that raises an exception, e.g. the following test.py:

def foo():
    raise ValueError()

foo()

2. Run python -m pdbp test.py
3. Allow the execution to continue by running continue. The debugger will stop at the line with raise statement.
4. Run restart. The pdbp session will terminate.

Expected outcome:
Program restarts as with original pdb.
