Karim was also astounded to find that IBM had a remarkably
similar product, and he apparently never looked at Oleg Subbotin's MS 
thesis in which he traced RTLinux threads or  Ismail Rippoli's 
RTLinux graphing tool (http://bernia.disca.upv.es/~iripoll/), or
read my 1996 paper on tracing Linux file system behavior or ... 

Shockingly, many of these projects use the same method of spooling data
in a buffer and having a daemon empty the data -- in fact, somehow Linux has
been doing this for syslog for many years. 

Next month, when someone else from Lineo invents local variables or
the letter "a", we will undoubtedly see yet another one of these strange 
episodes.
