+    When USE_SIGBUS_HANDLER is set to 1, a handler for SIGBUS will be
+    installed, which allows us to recover when there is a read error
+    when accessing an mmap'ed file. However, since the kernel folks
+    don't seem to like it when non kernel folks install signal handlers
+    in their own process, this is currently disabled.
+    Without the handler, the process hosting this service will die and
+    then be restarted. This is mostly OK right now because the process is
+    not being shared with any other services, and clients of the service
+    will be notified of its death in their MediaPlayer.onErrorListener
+    callback, assuming they have installed one, and can then attempt to
+    do their own recovery.
+    It does open us up to a DOS attack against the media server, where
+    a malicious application can trivially force the media server to
+    restart continuously.
