I'd do it the way you have done, but I wouldn't call it 
'avgPagesPerHost', since it's a bit misleading, but something along the 
lines of 'perHostLimit'.

I'd write the if/else version as:

if numPagesFetched != 0:
     perHostLimit = ...
else:
     perHostLimit = 42

But since here the standard case seems to be the first one, I think a 
try/except solution is both clearer and more efficient.
