Summary: "pausing" the VFS disassociates it from SQLite and

|

|

"Pauses" this VFS by unregistering it from SQLite and
|
||||
relinquishing all open SAHs, leaving the associated files intact.
|
||||
This enables pages/tabs to coordinate semi-concurrent usage of
|
||||
this VFS. If this object is already paused, this is a

no-op. Returns this object. Throws if SQLite has any opened file

Restores the VFS to an active state after having called

strategy for that type of error, but if the problem is simply
|

that the OPFS files are locked, then a later attempt to unpause

it, made after the concurrent instance releases the SAHs, may

recover from the situation.
