[Shootout-list] Mono timings correct for tcp* tests?

[Isaac Gouy]

>From Dave's next experiment it seems like we're timing the server
process alone?


# time tcl tcpecho.tcl 10

real    0m3.760s
user    0m0.777s
sys     0m1.130s

Looks like I get about the same thing for TCL. If I insert a timer
inside the client block of the mono code (I'm not real familiar with
TCL so haven't done that), the internal timer reports back ~3.6 seconds
alot closer to the 'real' time than the user+sys time.
