Re: [boost] [thread] Proposal for thread safe initialization of local static and global objects

Roland,

I've only scanned over your code - and I think this is a good idea, and a 
step in the right direction- but I did notice that you needed two calls to 
call_once?  One of the gripes I've had about call_once was that it was 
rather a heavyweight call: is this still the case?  Do you have any feeling 
for how efficient this approach is compared to say a statically initialised 
mutex (assuming that's what you want) ?

Thanks,

John.
