Remove a darwin-specific workaround for read()

Browse Source 
Because of a buggy realloc() implementation in earlier versions of
Python on Mac OS X, we had to cut reads into manageable chunks by hand;
this is no more needed with Python 2.6, and besides it causes problems
with imaplib2, which we now use. Revert the special case to use the
system's read() instead, which is now safe.
