- * cv_waiters is used for all the threads waiting to acquire the monitor

- * - As of Solaris 10u4, we can request that Solaris raise the 256
- * stdio fopen limit by calling function enable_extended_FILE_stdio,
- * (also done by hotspot). We check for its availability.
- *
- * - If we are stuck on an old (pre 10u4) Solaris system, we can
- * workaround the bug by remapping non-stdio file descriptors below
- * 256 to ones beyond 256, which is done below.
- *
- * See:
- * 1085341: 32-bit stdio routines should support file descriptors >255
- * 6533291: Work around 32-bit Solaris stdio limit of 256 open files
