[plt-scheme] Creating a suspended thread

Hi,

I'm tryring to create a thread which is initially suspended.  As far as
I know, (thread (lambda () ...)) creates a thread and runs it instantly.
Is it possible to create a thread in suspended state to resume later?

I know it's possible to create and suspend it afterwards but our
application is rather time intensive so I don't want it to have even a
little chance to run.

I might solve it using some kind of a locking primitive but I think it
would be an overkill to do it that way.

Any suggestions?
