I have just finished building RELENG_8 from a fresh csup on one of the three servers: I plan to isntall it in the morning (bed time now). Another thing I did was to patch the sendmail build config on another one of the servers, and rebuild, so that sendmail's sleep() would simply call FreeBSD's nanosleep(2). I have asked on comp.mail.sendmail if anyone knows why the sendmail build only enbles use of nanosleep on Solaris.
