I did some more investigation, the hang is caused by this call:
DECLCALLBACK(int) Console::saveStateThread(RTTHREAD Thread, void *pvUser)
int vrc = VMR3Save(that->mpVM,
after 0% was printed out, VMR3Save() never returns.
Interestingly, the freeze might to do with 2D accleration, because if I disble 2D acceleration, it does not occur that often.
The freeze won't occur if doing saving state from the vm GUI console, the Close button.

when 2D acceleration is enabled
c:\virtualbox-dev\vbox\out\win.x86\release\bin>VBoxManage.exe controlvm vm1 savestate
hangs after 0% is displayed.
If doing from the Close menu, after dialog box is displayed, then choose Save State, then works well.
I tried to break the code, it seems stop inside some Windows message loop.
This is very annoying. need to fix these crash bugs when vm is shutting down.
