+// Debugging class for that tries to add userspace logging for fence depencencies.
+// The model that a DependencyMonitor tries to follow is, for each access of some resource:
+// 1. There is a single ingress fence, that guards whether a resource is now safe to read from
+// another system.
+// 2. There are multiple access fences, that are fired when a resource is read.
+// 3. There is a single egress fence, that is fired when a resource is released and sent to another
+// system.
+//
+// Note that there can be repeated ingress and egress of a resource, but the assumption is that
+// there is exactly one egress for every ingress, unless the resource is destroyed rather than
+// released.
+//
+// The DependencyMonitor will log if there is an anomaly in the fences tracked for some resource.
+// This includes:
+// * If (2) happens before (1)
+// * If (2) happens after (3)
+//
+// Note that this class has no knowledge of the "other system". I.e., if the other system ignores
+// the fence reported in (3), but still takes a long time to write to the resource and produce (1),
+// then nothing will be logged. That other system must have its own DependencyMonitor. Conversely,
+// this class has imperfect knowledge of the system it is monitoring. For example, this class does
+// not know the precise start times of reading from a resource, the exact time that a read might
+// occur from a hardware unit is not known to userspace.
+//
+// In other words, this class logs specific classes of fence violations, but is not sensitive to
