There's a library (a resource actually, but there's not much
difference) which allows an application to gain and relinquish
exclusive access to that memory.

It won't be able to use the OCM if some other task has already
obtained access to it.  In the case of lwc, it will fail over to using
main memory. NetSurf here has always been restricted to one instance
(running it twice signals the first instance to open another window)
