Description
In these sections of the concurrency FAQ:
http://docs.mongodb.org/manual/faq/concurrency/#what-type-of-locking-does-mongodb-use
http://docs.mongodb.org/manual/faq/concurrency/#how-granular-are-locks-in-mongodb
The information is not up to date on locking with 3.0 and WiredTiger, since mmapv1 now offers collection-level locking and WiredTiger offers document-level locking. It's vexing because this FAQ is where we point community members with basic questions about concurrency like "can I write to collection x and y at the same time in 3.0?"
(Pardon if this is a duplicate- seems like it should've been picked up by now but a search didn't turn it up)
