[Sbcl-devel] MAKE-ARRAY :STATIC-P

[Nikodemus S. <nik...@ra...>]

As I mentioned a while back, callbacks are going to need some form of 
static (unmovable by GC) storage. While I _could_ just mmap some space, 
etc, I was thinking this would be a nice general purpose extension: add 
:STATIC-P keyword to MAKE-ARRAY which makes it allocate in static space.

Of course this makes the memory utterly unreclaimable, but for some 
applications -- such as callbacks -- that is ok. Allocating in the static 
space is nice at it allows us to do this for simple-arrays of arbitrary 
element-types without hacking the collector(s). I would at this stage 
leave DELETE-STATIC-FOO as a future extension when and if it becomes 
needed.

Assuming a sane implementation of this, are there any objections to
such an extension?

Cheers,
