First experince of Dtrace on Solaris 10

Well, as the work of getting nasty bugs fixes to be in before Solaris 10 FCS, this week is almost the first time I explore Dtrace to do things that truss nor dbx can not achieve. To debug something like what happen to your program when the network cable is snapped. While I have not been able to get all the information I need, that is to find out why a particular pollsys comes from and why it uses more times than others. I find it is surprisingly intuitive, even though at first it is rather scarely.

Definitely a must learnt thing for anyone is doing any bug fixes in Solaris.
