documented key :value is invalid for function fb-thread:make-mutex

[Jim Newton]

Looking at the documentation at http://www.sbcl.org/1.0/manual/Mutex-Support.html#Mutex-Support
I see the following documentation for the make-mutex function

— Function: sb-thread:make-mutex &key name value
Create a mutex.

However when I try to call (sb-thread:make-mutex :value t)
I see that there is no such key available.
Slime tells me the valid keys are (name %owner).

What do I expect to happen? I expect (sb-thread:make-mutex :value t) to return a mutex whose value is t.

I took a look at http://www.sbcl.org/manual/index.html#Threading
which claims the following.

Function: make-mutex [sb-thread] &key name %owner state
Create a mutex.

Nevertheless, my sbcl (which I updated and build a couple of weeks ago) does not have :state as a valid parameter to this function.

You do not have sb-thread compiled.

With best regards, Stas.

Do I have sb-thread compiled? Sorry, I don't know what the question means.
I have indeed recompiled sbcl to enable multithreading, and I do indeed have the package named :sb-thread available and loadable. Is either of those the answer to your question?

This option is only available if sb-thread is enabled. And it's a private option. And I just removed it.
