Does "options P1003_1B_SEMAPHORE" still exist?

[Paul Goyette <paul%whooppee.com@localhost>]

I recently noticed that there is a built-in "ksem" module that includes 
sys/kern/uipc_sem.c

The man page for sem(4) states that this code should be included in the 
kernel only if "options P1003_1B_SEMAPHORE" is defined.  Yet a search of 
the kernel sources shows no usage for this option anywhere, and the 
uipc_sem.c file is unconditionally included by sys/conf/files

So, I have a few questions:

1. Should sem(4) really be in manual section 4?  It doesn't appear to be 
a device driver!  (Maybe a more detailed man page should be written for 
section 9?)

2. Should the man page be updated to remove the reference to the option?

3. If the code is truly unconditional, should it really be a module?  If 
so, could it be made to auto-load when needed?  Could it also be auto 
unloaded?
