No.
Synchronize does not depend on the GUI, it does depend on the main
thread calling CheckSynchronize from time to time.
The main thread in a lazarus program handles the GUI, and when the GUI
is idle, it calls checksynchronize for you. That's why it works 'transparantly'.
In a DLL you must make sure that the main thread calls CheckSynchronize
from time to time. This usually means exposing a command that does this,
and letting the main application call this command from time to time.
