Sorry, but I'm -1.
I don't feel comfortable with adding a such amount of intrusive code,
which will have to be maintained as the interpreter evolves, to add
probes just for Solaris derivatives, which is, with all due respect,
really a niche platform. So If we merge this, this should at least
support SystemTap upfront.

You can already go a really long way with just strace and oprofile, I
don't really but the performance optimization argument.
Also, I must admit I'm quite skeptical about the real benefit of
explicit probes for user-land, especially for CPython which isn't used
for performance-critical systems...
