Problem Description: 

Bugs corrected in revision 02:

4019273 - mirror not synchronizing properly with ODS 3.0 or ODS 4.0

	In some circumstances, when an application is modifying pages
	as they are being written, submirrors may momentarily contain
	different copies of data. This fix narrows this window to a
	much smaller time.

Bugs corrected in revision 01:

1253688 - system watchdog resets due to ERROR_MODE_RESET

	In very rare cases when mirroring swap, watchdog
	resets may occur on SRMMU (sun4m, sun4d) machines.
