I came over a discussion on slashdot about an effort to implement
solaris dtrace for FreeBSD (sorry if this is not the news), the article
discussed:

http://www.zdnet.com.au/news/software/soa/Developer_aims_for_Dtrace_on_FreeBSD/0,2000061733,39210618,00.htm

On a somewhat related note (solaris): I also saw a posting in
threads-related newsgroup about something called "cyclic subsystem" in
solaris for high-precision timimg:

http://blogs.sun.com/roller/page/eschrock?anchor=inside_the_cyclic_subsystem

Looks quite interesting, although probably not a "junior hacker's" level.
