Instead of sleeping, how about wait/notify?
In the VM startup:
if (debugging enabled)
synchronized (whatever)
while (! thread1_started || ! thread2_started)
whatever.wait();
Then each thread will synchronize, set their flag, and notify().

It is always useful to write pure java reference code which works in
common situations, and which can be used as a guide. VMs with unusual
constraints typically have to look out for themselves a bit.
