| /* Dispatches events to input targets. Some functions of the input dispatcher, such as |
| * identifying input targets, are controlled by a separate policy object. |
| * |
| * IMPORTANT INVARIANT: |
| * Because the policy can potentially block or cause re-entrance into the input dispatcher, |
| * the input dispatcher never calls into the policy while holding its internal locks. |
| * The implementation is also carefully designed to recover from scenarios such as an |
| * input channel becoming unregistered while identifying input targets or processing timeouts. |
| * |
| * Methods marked 'Locked' must be called with the lock acquired. |
| * |
| * Methods marked 'LockedInterruptible' must be called with the lock acquired but |
| * may during the course of their execution release the lock, call into the policy, and |
| * then reacquire the lock. The caller is responsible for recovering gracefully. |
| * |
| * A 'LockedInterruptible' method may called a 'Locked' method, but NOT vice-versa. |
