I want to make sure about the semantics of unshared variables.
import std.concurrency;
import core.thread;
ubyte[1024 * 1024] buf1MB;
void fun() { Thread.sleep(5000.msecs); }
void testThread() {
foreach(i; 0..2000) {
spawn(&fun);
}
}
Are instances of buf1MB created for every threads?
Even if it is never accessed by the threads?
If some static variable is defined in other module
or in some library, all of them also instantiated
for every threads?
BTW, calling testThread() above causes following
run time error. Is this an expected result?
core.thread.ThreadError@src\core\thread.d(2903): Error creating
thread
