I just read in the release notes that 5.3-RELEASE has the new ULE scheduler available, but that 4BSD is the default scheduler. I thought I read messages in freebsd-current indicating that the option to use ULE was completely removed from the 5.3 or even the RELENG_5 branch? So, is ULE really available? -- Thomas T.
