Nate,
thanks for your support and prompt reply again.
I tried the following code change.
def ClockTest() {
val c = Clock.make();
finish for (p in Place.places ) {
async (p) clocked (c) {
Console.OUT.println("Before next");
next;
Console.OUT.println("After next");
}
c.drop();
}
}
This got me the following output.
<map>
<host name="sirius" slots="1" max_slots="0">
<process rank="0"/>
<process rank="1"/>
</host>
</map>
<stdout rank="0">main: before ClockTest</stdout>

Your explanation still sounds reasonable to me. Is something wrong with the
X10 runtime ?
