> When a thread receives an interrupt Derby detects this, it will reset the
> thread's flag and save the fact in its lcc (LanguageConnectionContext), if
> available. If not (e.g. during boot) it will save the information in a thread
> local variable. For performance reasons, we use the lcc when available.
> However, when shutting down the database, the lcc goers away, and when the
> JDBC call returns to the application, the thread's interrupt flag will not be
> reinstated as per our specification. This is because the lcc dies before we
> do the restoring (under shutdown). So, the information that the thread was
> interrupted is lost with the lcc going away. A possible solution is to move
> the flag over to the thread local variable when the lcc is popped, so that
> the restore code will find it.
