Summary: a probe never completes, an exception is displayed

Initial Comment:
It can occur that a probe doesn't complete while its execution duration has
elapsed.
An exception is displayed in the terminal:

     [java] CLIF server xxxx is ready.
     [java] Exception in thread "CLIF probe"
java.lang.IllegalArgumentException: timeout value is negative
     [java]     at java.lang.Thread.sleep(Native Method)
     [java]     at
org.objectweb.clif.probe.util.AbstractDumbInsert.run(AbstractDumbInsert.java:320)
     [java]     at java.lang.Thread.run(Unknown Source)

It is not deterministic whether this problems occurs or not. Maybe a heavy
system load induces a greater risk.

The problem comes from a negative thread sleep occurring in
rare circumstances, and causing the probe thread to abort
(and then never reaching a "final" state, be it completed or
failed).
Fixed in 1.3.0 branch (commit 1581) and in trunk (commit 1580).
