    11 /*

    12 This is strictly implementation specific test for dom storage code from bug 600307.

    13 It exercises code for asynchronous data flushing with regard to cache life time and its preload.

    15 "flush + reload" means to tell the database to store all pending data then wipe the cached content and reload it from the db

    17 "reload" only means to simulate situation when there is a pending flush for an origin but a new cache is about to preload

    18 which is a corner case happening rarely ; this helps check the next preload operation will load correct data from the database anyway

    20 Case 1: set | flush + reload | remove | set | remove | flush + reload | get ?= null

    21         checks coalescing optimization for single key changes does work correctly for repeated removals of a key

    23 Case 2: set | set | clear | flush + reload | count ?= 0

    24         checks whether clear operation superseeds setting keys, the database must be empty for the origin

    26 Case 3: set | set | clear | reload | count ?= 0

    27         check the corner case when a data clear flush is pending but a new cache is about to preload
