May be the license manager can be configured to set some "lease time"
which would avoid the network message for each compile command.

I think Flexlm has some "TIMEOUT" option for that  and may be other license
manager has the same kind of option.

Setting a 2 sec lease time should be enough to avoid the "check for
license" overhead.
