# This test is not run automatically.

|
|
# It requires > 2gb memory for the >2 gigapixel image generated in the
|
|
# second test. Running this automatically would amount to a denial of
|
|
# service on our testing infrastructure. I expect this test to fail
|
|
# on any 32-bit machine, as well as any smallish things (like
|
|
# Raspberry Pis). It does succeed on a 3gb Ubuntu 12.04x64 VM on Python
|
|
# 2.7 and 3.2.
