the resource ids of the tokens whose sockets this object holds
how many sockets are held
closes every held socket and forgets them
through the LF, terminator included (readLine strips it); null at EOF
dials the endpoint and keys the socket by the token's resource id
exactly max bytes via readN, as a self-describing reply needs; null at EOF
writes the chunk and returns its length; 0 for an unknown id
The sockets one interpreter holds, by token resource id; per object, as
pib_runhas no request shutdown. The interpreter drop must call closeAll.
