bnet and Threads

These bnet routines work fine in a threaded environment. However, they assume that there is only one reader or writer on the socket at any time. It is highly recommended that only a single thread access any BSOCK packet. The exception to this rule is when the socket is first opened and it is waiting for a job to start. The wait in the Storage daemon is done in one thread and then passed to another thread for subsequent handling.

If you envision having two threads using the same BSOCK, think twice, then you must implement some locking mechanism. However, it probably would not be appropriate to put locks inside the bnet subroutines for efficiency reasons.
