So we guess you say you've already done the following too:
PastryNode pn = ...
synchronized (pn) {
while (!pn.isReady()) {
try {
pn.wait();
} catch (InterruptedException e) {
System.out.println(e);
}
}
}
We should not do polling with PastryNode#isReady() because we can
Object#wait() on an instance of PastryNode.

Anyway, on FreeBSD, even polling should perform as well as on Linux
and Windows.
