use mike's "don't set to blocking before closing unless needed" patch?
take a look at DB's smtp patch (add "extra argument" table)
move wsocket.c:sock_send kludge to buffer.c:sendraw (probably)?

optmize aux_getgroupudata (Mike idea)
    make aux_newclass receive upvalues
    use one upvalue per string name of class/group
    make aux_checkgroup by upvalue (faster)

add error message stuff to the manual

make sure all modules that can use it actually use socket.newtry
adicionar exemplos de expansão: pipe, local, named pipe
testar os options!
- Thread-safe
  - proteger get*by*.* com um mutex GLOBAL!
  - proteger ou atomizar o conjunto (timedout, receive), (timedout, send)
  - inet_ntoa também é uma merda.

*create the getstats method. 
*fix local domain socket kludge of name size
*use TLS 
*sort out the wrap around of gettime...
 *use doubles all over
 *sock_send, sock_recv & sock_select use p_tm instead of timeout
 *make select interrupt safe (will be with tm stuff)
 *use GetSystemTimeAsFileTime in windows (WinCE will suffer document)
*add getstats to the manual
*Fazer compilar com g++
*test associativity of socket.select
* fix manual for send and receive
* add thanks to mike
* change sock:send to use indices just like string.sub?
* change sendraw to send by chunks
