If you read this message why do you ask? How do you address my concerns?

It wouldn't work standard library does not have 1/4 of what I need or
provides inconsistent functionality - even in basic threading library
- have you notices
for example shared lock and recursive shared lock ;-)... It is there
for purposes.

Not it wouldn't but in some special cases. Only stuff that really may
give some performance gain in C++11 is move constructor
the rest does not relay to performance.

This is exactly the core issue - we... it isn't we it is me... so far
there is virtually 0 contributions
by the community I have received only from very few users there.

As I explained I do want to support C++11 but without dropping C++03 support.

For example booster::callback and booster::function is 100% compatible
with C++11 lambdas.
Also what is "needed" is probably adding move constructor but not much.

Bottom line - in most of the cases I write using CppCMS I do write in C++11...

To be honest I have much urgent stuff to do with CppCMS rather than
waste the time on code migration.
