The configured path is used for synchronizing access to the shared memory
segment among the various server processes.  The default shared memory
segment size allocated is 1.5MB; use the optional <em>size</em> key to
configure a different size, in bytes.  Note that the configured size
<i>must</i> be able to hold at least one cached session; if a too-small size
is configured, that size will be ignored and the default size will be used.
