You cannot wrap the async_write call to catch the error. Instead the 
async_write takes a WriteHandler which is called on completion of the 
write operation. This handler takes a parameter of type error_code which 
is used to signal errors. See
http://www.boost.org/doc/libs/1_35_0/doc/html/boost_asio/reference/async_write.html
and
http://www.boost.org/doc/libs/1_35_0/doc/html/boost_asio/reference/WriteHandler.html
