Byron,

THanks for that.
Seems reasonable except for the catch(std::bad_alloc&) ... I'm not  
sure it's good MoJo to catch that. Given our amazing reliance on the  
heap, a failure to allocate is a serious problem. I'm more tempted to  
subclass the allocator and create 'transport buffers' as a type that  
we can define an allocator for. Then we can put a limit on the amount  
of memory in play for transport buffers WITHOUT jepordizing the  
operation of the rest of the stack. I realize this is something of a  
change, but it is far safer than implementing a catch of bad_alloc  
when std::operator new(size_t) the the thrower....

My thoughts,
