I do not believe the current status of DTrace is appropriate for promoting
1. DTrace is an experimental function or Semi-finished products. The kernel
dtrace support is ok, but the userland support is far from completion(at
least the pid provider has many bugs)
2 the FreeBSD implementation is different from Solaris/Mac OS X. The
DTraceToolkit, which has many amazing feature, can not 100% works on
FreeBSD, and there is no doc to identify the difference.
3 There is a missing feature list about DTrace, but no schedule list about
when to fix it.
