Hi Compiler Developers,

foreword: please forgive if this is too low-level etc or if I don't understand
it enough ;)

Since I'm glancing over lkml sometimes, I couldn't help but notice
an announcement by Stefani Seibold, that a fast, reliable userspace timestamp
function(s) are on the process to land in the Linux kernel.

The mechanism is said to be using VDSO (http://en.wikipedia.org/wiki/VDSO sorry
for wikipedia link... so lame I had to look it up ;) )

This being targeted to the 'development' kernel(s) so far, may be a bit
off the charts, (but then the announcement says x86_64 has it already in glibc)
any chances FPC could make use of it when it actually lands in user-visible configurations?

See the announcement here

Curiously,
-L.
