Description
In this DOCS reference: http://docs.mongodb.org/manual/core/index-creation/#index-creation-background
Please amend the DOC to add clarity on index build behaviour, in particular the following statements:
A foreground index build is default, when complete on a replica set primary, it'll replicate to the secondaries with a foreground build task. The replication worker will take a global DB lock, which will queue reads and writes to all DBs on that server.
A background index build, when complete on a replica set primary, it'll replicate to the secondaries with a background build task. The replication worker will not take a global DB lock. Secondary reads will not be affected.
