Summary: Shmem serious bugs

Initial Comment:
Hi,

these are the 2 things I have found so far using the 
shmem lib.

My understading is that this is not yet a boost 
library but it has been accepted to become one in the 
near future. Accept my apologies if I shouldn´t had 
posted here.

 1) If you try to use a node allocator with a 
fixed_named_shared_object it won't compile. Works fine 
for non fixed segments.

 2) If you concatenate with the '+=' operator a 
boost::string with a NULL terminated str (char *) in a 
loop up to N times, you get bad_alloc sooner than if 
you do a single allocation of the same lenght of the N 
previous allocations. So concatenating is wasting 
memory somehow, as you can allocate longer strings 
with a single allocation than with N equivalent 
concatenations.

Thanks.
