This could be done by installing a kernel driver that would use 
PsSetCreateThreadNotifyRoutine (if I remember the name correctly) to 
register a callback that would use an IPC mechanism to notify druntime 
about new threads created by the system. Chances that this approach will 
be adopted by druntime are less than zero.
