[PyQt] How to handle circular imports

Hey there.
I have a problem regarding sip that I guess is probably trivial.
I have an C++ API which is contained in one library file. I am over half way
though making python bindings. In the process of making these bindings I
decided to split them op into 7 modules that each handle there logical
partition of the problem domain, ie UserService, GroupService, RoleService,
etc.
Until now it has been smooth, I created sip definitions for 20% of the
UserService module and when implementing the RoleService I needed
specifications from the UserService (UserItem) so I %Import'ed the UserService
Module in RoleService. Everything worked as it should.
Then when I wanted to define the remaining 80% of the UserService module I
also needed definitions from RoleService in UserService (RoleItem)... But,
but, but here I ran into problems, cause when I in the RoleService module's
sip definitions already imported UserService, I got a circular import when I
started importing RoleService in UserService.
Is this possible to work around?
the prob:
this is what happens in sip while processing module A:
A imports B which then import A
cause A depends on specs from B and B depends on specs from A
