Yes -- this is exactly what I have in mind.  Today, the flags simply indicate 
memory allocation disposition, but I think it's reasonable to assume that like 
several other complex object allocators/initializers, we might want additional 
flags in the future.  I think I prefer the sf_buf_alloc() model (custom flags 
mapped as needed into underlying operations), rather than the soalloc() model 
(reuse some but not all memory flags).
