+##### Access to ktr(4) buffers via shared memory
+Our event tracing system, ktr(4), records interesting events in per-cpu buffers that are printed out with ktrdump(8). Currently, ktrdump uses libkvm to access these buffers, which is suboptimal. One can allow a sufficiently-privileged userspace process to map those buffers read-only and access them directly. For bonus points, design an extensible, discoverable (think reflection) mechanism that provides fast access via shared memory to data structures that the kernel chooses to expose to userland.
