possible performance issue with netCDF3 files

I believe I may have discovered a performance issue, although it may well
be a case of me doing something unusual. I have created a minimal test
case, attached.

In the attached script, I create a netCDF3 classic file, with 3 dimensions,
and create 100 variables, each with a single attribute. As you should be
able to see from the output of the script, the time taken to insert each
attribute grows rapidly - at the end, it is taking about 10 seconds to
insert a single attribute. However, if I set the output format to NETCDF4,
the problem goes away.

My software versions:
netCDF 4.0.1
netcdf4-python 0.8.2
hdf5 1.8.1

Attachment: test.py
