> Currently, if a client is writing to multiple ledgers and these ledgers
> overlap on some bookie, there will be as many threads for such a bookie as
> the number of ledgers writing to it. Consequently, if a client writes to many
> ledgers simultaneously, it may end up with an undesirably large number of
> threads. I don't have a concrete proposal yet, but I suspect it is as simple
> as keeping an array of BookieHandle objects, one per bookie, and having each
> BookieHandle object shared by all ledgers.
