Question: Is this library routine-safe?

[lv-zheng]

Can I use one database handler in multiple routines concurrently? Or should I open a handler per routine?

select query should work but insert/update maybe not without mutex.

I think this can be mentioned in FAQ, as there are many issues about concurrency, to name a few, #50, #209, #51
