 * We sometimes hand clients objects that contain mapped buffers. The client may consume
 * the mapped buffer on another thread. This object manages receiving messages that buffers are
 * ready to be unmapped (on the owner's thread). It also handles cleaning up mapped
 * buffers if the owner is destroyed before the client has finished with the buffer.
 *
 * Buffers are first registered using insert() before being passed the client. process() should be
 * called periodically on the owner's thread to poll for messages and process them.
