 I am not really familiar with the code. So am I correct in making the
following assumptions?

* It is not easy to fix the C api to reset the iterator (what about
repeating the search?)

* The only accurate way to get the number of messages is to iterate through
every search result and count them?

If so, then len(...) I think might be very slow if there are a large number
of elements.

Maybe it might be easier/better to implement object.__nonzero__(self)
 instead of the object.__len__(self) method?

http://docs.python.org/reference/datamodel.html

object.__nonzero__(self)
Called to implement truth value testing and the built-in operation bool();
should return False or True, or their integer equivalents 0 or 1. When this
method is not defined, __len__() is called, if it is defined, and the object
is considered true if its result is nonzero. If a class defines neither
__len__() nor __nonzero__(), all its instances are considered true.

object.__len__(self)
Called to implement the built-in function len(). Should return the length of
the object, an integer >= 0. Also, an object that doesn’t define a
__nonzero__() method and whose __len__() method returns zero is considered
to be false in a Boolean context.
