It is atomic with respect to other rules firing; only one rule can be
firing at a time. It's not atomic with respect to working memory
changes, though; working memory can be changed by other threads while
the RHS of a rule is executing.

Hi,
Execution of a rule RHS is sequential. But is it atomic?
In other words, during that time, is it possible that other
activated rules get fired?
These activated rules include those that had been on the agenda or
newly activated rules due to pattern matching caused by the RHS
invocation of modify, assert or retract.
Any feedback is greately appreciated.
