Push maintype down the module heirarchy- up to an including creating a 
special module which only contains maintype (and some supporting 
functions), which everything depends upon.

More generally, refactor your code.  Find hunks of code which are already 
mostly independent and consider how to make them more independent, so you 
can cut them out into their own modules.  Limit interactions between 
different parts of the code, and develop interfaces for those interactions 
which are necessary.  This actually leads to more maintainable code.
