Hi Eric,

So you try open database, and it meet some problems,
And probably throw exception, start close db files back...

I have only one idea.

The file of db was already opened by other session or app.

Me and Totte it seems have see bug in OS X file system, when OS X still
think that file is opened although it was closed already. Some bug in cache
system...

BTW, you can try reproduce this, if EXPLICITLY open your db in VAPP,
And now start your app, so your app must fail to open db,
But it must not crash!

Check this.
