For regular lists:

In [11]: list(range(50))
Out[11]: 
[0,
 1,
 2,
 3,
 4,
...
 46,
 47,
 48,
 49]

However:

In [13]: collections.UserList(range(50))
Out[13]: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49]

The notebook has its own internal idle-culling mechanisms, including shutting down idle kernels, shutting down itself when there's been no activity, and making decisions based on whether there are open connections or not. This is a lot more sophisticated, and offers much more granularity than the network-activity-based activity we have now.

For reference, we enable this config [on mybinder.org]

Hi,

In regard to @n-riesco 's comment "please could you also confirm that the file %APPDATA%\jupyter\kernels\javascript\kernel.json":
I don't seem to have the folder kernels. (I guess that explains why Atom says it can't find the kernels?)

Elevator Pitch

Code defined in a %%time cell doesn't appear to be recognised so you then get spurious warnings about e.g. undefined variables.

Motivation

Spurious warnings detract from the utility of a code linter

Design Ideas

I think this is a hard problem t
