r8219: Merge the new open code from HEAD to 3.0. Haven't yet run the torture
tests on this as it's very late NY time (just wanted to get this work into the tree). I'll test this over the weekend.... Jerry - in looking at the difference between the two trees there seem to be some printing/ntprinting.c and registry changes we might want to examine to try keep in sync. Jeremy. (This used to be commit c7fe18761e2c753afbffd3a78abff46472a9b8eb)
