Slightly OT -- I put the check for the length of the path in there 
because otherwise pycairo/cairo segfaults, and I thought an exception 
would be preferable to a segfault.  That limit was obtained through 
experimentation, and might not be accurate (I couldn't actually find a 
hard limit in the cairo code, it's more likely due to an interaction of 
multiple parts of the code).  This was all true with Cairo 
1.4.10/pycairo 1.4.0.  With other versions this may not be the case, but 
my "catch" happens regardless.  We may want to revisit that if we 
discover that newer versions of Cairo can handle longer paths.

Cheers,
Mike
