LibGAlloc GrayOps API
=====================

The *external* API encourages people to use *properties* to define
resources, and will mask the extension users away from working
directly with resources and resource lists.  The following functions
are *gray ops* functions.  They are mainly for use by extension
authors who have included also the internal utility functions in
`internal/galloc.h` in order to do some fancy managing of request
lists, but they are not so obscure that others may not have occasion
to use them, and can be used without `internal/galloc.h`.  See
`ga_prop.h`.

Not there yet.
