/**
|
|
* An asynchronous SQL statement. This differs from mozIStorageStatement by
|
|
* only being usable for asynchronous execution. (mozIStorageStatement can
|
|
* be used for both synchronous and asynchronous purposes.) This specialization
|
|
* for asynchronous operation allows us to avoid needing to acquire
|
|
* synchronization primitives also used by the asynchronous execution thread.
|
|
* In contrast, mozIStorageStatement may need to acquire the primitives and
|
|
* consequently can cause the main thread to lock for extended intervals while
|
|
* the asynchronous thread performs some long-running operation.

|
|
* This does not work for BLOBs. You must use an explicit binding API for

|
