Versions 8.5 and 8.5.1
LotusScript is thread safe; multiple LotusScript Web agents can run concurrently within the Domino server.
A thread is an instance of LotusScript, in this case an agent. All threads execute in the same memory space. LotusScript threads have no protection against updates on global variables or contention on the various internal data structures. By running multiple agents, you synchronize instances of LotusScript running against each other.
LotusScript agents run as separate threads in the same HTTP process. A process is a collection of one or more threads executing a single application.
Context switching is the act of saving the current state (hardware and software) and switching to another thread or process by restoring its state.
A time slice is the amount of time given to a thread or process to execute before switching context to the next thread or process.
A thread is blocked if a necessary resource is unavailable.
An atomic update is one in which another thread observing the update always sees a complete update and cannot interfere.
