option 1: make the subscriber listen for an event that has a request  
attribute (perhaps one you generate).
option 2: see if there's another way to do what you want
option 3: grab it by force from the thread locals--something like this:

import zope.security.management
from zope.publisher.interfaces import IRequest

def getRequest():
     i = zope.security.management.getInteraction() # raises  
NoInteraction
     for p in i.participations:
         if IRequest.providedBy(p):
             return p
     raise RuntimeError('No IRequest in interaction')
