Freeze and Resume execution

[BruceKL WhoH]

I come across the same problem. 

What I want to do is to write a vim script to debug python script. Bdb(exactly, a derived class of Bdb) will be called, and when it break at some breakpoints, it must freeze, and come back to vim, then later, user will call 'step' or 'trace' or 'continue', then Bdb will be called again and resume.

Just last week I posted a mail to ask, but it seems that it's impossible to do it.
