[boost] scope_lock performance issue (followup)

Hello,

The previous performance tests on linux where done using a program 
compiled with g++ -O2

I just tried with -O5 and got better results for linux.
Note that Win32 test is on 800MHz computer and Linux test on 1200MHz 
computer. Sorry I don't have a dual boot machine around.

1° native calls:  65 sec (Win32), 104 sec (Linux)

2° using scoped_lock call: 185 sec (Win32), 153 sec (Linux)

3° using synchronize call: 68 sec (Win32), 105 sec (Linux)

The difference with scoped_lock is much more visible now.
The difference between linux and win32 can come from the dynamic 
libraries. On win32 everything is static on linux pthread and 
boost_thread are dynamic.
