Provides the implementation classes for the local: protocol for the HotSpot PerfData instrumentation buffer monitoring implementation.

The local: protocol is the default protocol for the PerfData implementation. It utilizes a name shared memory mechanism, identified by a backing store file in the file system name space. The location of the backing store file is platform specific and is dictated primarily by the JVM implementation. However, the `java.io.tmpdir` system property generally contains the location of the files, with the exception of the Solaris implementation, as the SDK and HotSpot JVM use different locations for their temporary file storage. The HotSpot JVM uses the /tmp directory and the SDK uses /var/tmp. The classes in this specifically use /tmp when running on Solaris.
