                 (The tests pass under Windows OS)
switch/Mode    : -Xprof -verbose -verify -Xfuture
                 (The tests pass with default switches)

Four JCK1.4-b09 runtime api/java_net tests hang and fail because of timeout when running
in "-Xprof -verbose -verify" mode.

Probably, this bug is a duplicate of #4461173.

How to reproduce:
====================
Run the following script under RedHat Linux 6.2
(probably, you need to change JCK and JAVA_HOME paths):
--------Script START---------------------
#!/bin/sh
JAVA_HOME=/net/jdk/export/disk8/local.java/jdk1.4/linux-i386
JCK=/net/jdk/export/disk8/local.java/jck1.4/JCK-runtime-14
export CLASSPATH="$JCK/classes:$JCK/javatest.jar"
executeClass="javasoft.sqe.tests.api.java.net.DatagramSocket.ReceiveTests"
$JAVA_HOME/bin/java -Xprof -verbose -verify -Xfuture ${executeClass}
---------Script END----------------------

EVALUATION Running tests on pea.east linux 6.2 zoot machine works fine. Also test on dogboy.east 7.1 linux machine. Not re-producible. Is this a single CPU issue, dual, or quad, etc.. Please Test on single, dual, quad processor machine PC's. ###@###.### 2001-09-19 I can dup it on my Linux box (single CPU 1G AMD). This hang is caused by a bug in hpi::timeout(). hpi::timeout() on Linux is implemented by poll() system call, and when poll() is interrupted by a signal, hpi::timeout() would restart poll(). However, hpi::timeout() should adjust its timeout value according to elapsed time when restarting poll(). Otherwise, if hpi::timeout() is constantly interrupted and everytime it uses same non-zero value to restart poll(), VM would hang in infinite loop of poll()'s. ###@###.### 2001-09-24 Fixes to correct hpi::timeout() were put back in addition to more general handling of EINTR (see 4178050 and 4425033, which should theoretically be possible on Linux but could not be reproduced). ###@###.### 2001-09-25
