What about a latent_write_lock?

It's semantics would be to block on contruction until it only shares the  
mutex with read_locks.  A write_lock could be contructed from a  
latent_write_lock and this would always work, because another  
latent_write_lock would still be blocked in it's constructor.  This kind  
of lock would be useful for situations in which you have to read a  
structure to know if you have to write on it.
