 some other regular expression engines. (We pay for this by disallowing
 features like arbitrary look-ahead and backreferences.)

+When a DFA is used, pathological cases with exponential state blow-up are
 avoided by constructing the DFA lazily or in an "online" manner. Therefore,
 at most one new state can be created for each byte of input. This satisfies

 proportional to the size of the input. As a stopgap, the DFA is only
 allowed to store a fixed number of states. When the limit is reached, its
 states are wiped and continues on, possibly duplicating previous work. If
