Summary: 100% CPU with thread in a loop
Product: D
Version: 1.053
Platform: x86
OS/Version: Linux
Status: NEW
Severity: major
Priority: P2
Component: DMD

When I create a thread in a while loop, the first time it is created it works,
the second time dual-core CPU gets up to 100% load and stucks in there. Tested
with DMD 1.053. When compiled with latest GDC, only one core gets to 100%, the
other one is fine.
Code:
class doNothing : Thread;
while(condition){
Thread test = new doNothing();
test.start;
test.wait(1000);
}
Reproducible: Always.
System: Ubuntu 9.10, x86, Core 2 Duo
The doNothing thread just wastes CPU cycles, I wrote it as a test for the
wait() method. The test instance gets terminated after the second that is
waited in wait().
