 * This file essentially replicates NSPR's source for the functions that

 * NSPR's functions, instead of duplicating them, but they're private.
 * As long as SSL's server session cache code must do platform native I/O
 * to accomplish its job, and NSPR's error mapping functions remain private,
 * this code will continue to need to be replicated.
