I don't know of a portable way for an inetd-style daemon to "listen" for

On some systems (including RedHat/Fedora and debian), you may be able to

This stupid code works for modules, but not for packages. It probably has bugs.
import marshal, types
class StringImporter:
def __init__(self, old_import, modules):
self._import = old_import
self._modules = modules
def __call__(self, name, *args):
module = self.
The curve may take a while, but I'd definately recommend it.
While you're at it, why not switch th front end to python too?

I do have to do everything you describe here in the current
implementation of my system. I realize that importing a pyc file and
compiling a string results in two different things. This is okay though
as I'm fairly sure this will still suit my needs.

How is your Firebird database configured -- Classic Server or Super
Server? If it's in classic server mode, you don't need to worry about
the host portion. You do need to worry about permissions on the
database file. I got it to work by making it 664 and owner + group

I wrote the following to prove to myself that
deepcopy would copy an entire dictionary
which contains an instance of a class to
one key of another dictionary.
Note that after copying adict to ndict['x']
I delete adict.
Then ndict['x'] contains a good copy of adict.
works great.
