Lots of import errors today

[Alex Epshteyn]

I'm seeing lots of DeadlineExceededErrors in production logs in recent
hours where the app seems to be stuck on loading various imports.

Examples:
1) File "/base/python_runtime/python_lib/versions/third_party/
django-0.96/django/template/loaders/filesystem.py", line 17, in
load_template_source
return (open(filepath).read(), filepath)
2) File "/base/python_runtime/python_lib/versions/1/google/appengine/
ext/appstats/datamodel_pb.py", line 20, in <module>
from google.net.proto import ProtocolBuffer
3) File "/base/data/home/apps/typeracerdata/62.354361981982300313/
encoding.py", line 1, in <module>
import time
etc..

I've never seen this before - in the past deadlines were usually
reached while waiting for datastore operations and that sort of thing.
