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
our time complexity guarantees, but can lead to unbounded memory growth
our time complexity guarantees, but can lead to memory growth
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
