Hi,

Thank you for writing about GroovyServ. Great!
I've read section 19.3 and found some points which may be incorrect.

1) P.295
- The Python version takes 0.3 seconds
+ The Python version takes 0.03 seconds

2) P.295

GroovyServ surely manages to handle the CWD,
but it's reason only for using JNA in groovyserver.
That's not a reason that groovyclient is a native command.
It's just only for startup speed and another technical reason: 'select' function.

If groovyclient is written by Groovy, ...it's nonsense (no improvement).
If groovyclient is written by ShellScript, there isn't the "select" function (cf. 'man select') by which groovyclient gets both the response from server and the stdin from console.

So, groovyclient must be written by C.
