[岳帅杰]

Hi, Tom:

	I got it.
	There is no particular reason I need to have multiple writer threads. 
	Thanks for your help!

Hi Ray,
WritableDatabase objects can only be used by a single thread.
Generally the best approach is to marshal all your writes into a
single structure (e.g. a queue or spool directory) and have a thread
or process to pick off items and write them to the database.
Is there any particular reason you want to have multiple writer threads?
cheers,
Tom
