if you look at the debug output (which you may already have done),
it's an obvious case of fragmentation-inducing behaviour. any malloc-
based system may choke on the sequence
for a large number of attempts:
allocate a 15 megabyte block
shrink block to a couple of kilobytes
occasionally allocate a medium-sized block
from what I can tell, replacing the
data = self.sslobj.read(size-read)
data = self.sslobj.read(min(size-read, 16384))
should do the trick.
