dtrace

[Andriy Gapon]

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:

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:

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