### 3.7 Set network properties

Loadable Function: network_set (connections, key, val)

  Set the property named by key to the value val for each machine specified by connections.

  This function can only be successfully called at the client machine. See `pconnect` for a description of the connections variable. connections can contain all connections of the network, a subset of them, or a single connection.

  Possible values of key: `'nlocaljobs'`: configured number of local processes on the machine (usable by functions for parallel execution); needs a non-negative integer in val, `0` means not specified.
