/**
|
|
* Basic test of killop functionality.
|
|
*
|
|
* Theory of operation: Creates two operations that will take a long time, sends killop for those
|
|
* operations, and then attempts to infer that the operations died because of killop, and not for
|
|
* some other reason.
|
|
*
|
|
* NOTES:
|
|
* The long operations are count({$where: function () { while (1) ; } }). These operations do not
|
|
* terminate until the server determines that they've spent too much time in JS execution, typically
|
|
* after 30 seconds of wall clock time have passed. For these operations to take a long time, the
|
|
* counted collection must not be empty; hence an initial write to the collection is required.
