1) apr_os_sock_put() should not be changed to do those syscalls.  Some 
callers use apr_os_sock_put() to make sockets and never need the local 
or remote names, and they shouldn't suffer the syscalls.

2) apr_os_sock_put() remembers that it doesn't know the remote and local 
names, so if the app ever queries for such info apr will do the 
getsockname() or getpeername() then.  So I wonder why you need to modify 
apr_os_sock_put() in the first place.  Maybe you found a hole in the 
existing logic to make the syscall if/when such info is queried?  If so, 
maybe that is what needs some changes.

3) Check out apr_os_sock_make(), which allows the caller to specify the 
remote and/or local address if for some reason you need the info known 
at the time the apr_socket_t is created.  The app would have to make the 
call(s), but if you're an Apache MPM don't you already know that 
information?
