[ros-dev] Re: [ros-svn] [ion] 15492: Nonpaged Pool Liberation Day: Allow PagedPool to be used earlier, allow fast mutex to be used earlier on debug builds. Allocate all Se stuff from PagedPool, set the right object types to use paged pool, allocate all strings from paged pool, allocate PE sections from paged pool, and a bunch of other things which should, imo, be in paged pool. If anyone has any contradicting proof, let me know...until then, enjoy ~4-6MB more NonPagedPool

I've some some testing:

1) Create ExEvent with Nt Function
2) Reference by handle
3) Print New NP Allocs + RefCount
4) Deref
5) Print RefCount
6) Close Handle
7) Print RefCount + Messages in ObpDeleteObject:

(ex/init.c:561) Creating event
******* Dumping non paging pool contents ******
Size 0x28 Tag 0x656e6f4e (None) Allocator 0x80048a45 => The 'hack' for 
creating the name. My next patch in my WC does this properly, I will 
probably commit it in the next 2-3 hours or so.
Size 0x50 Tag 0x6e657645 (Even) Allocator 0x80049982 => The actual Event
(ex/init.c:584) Refcount of New Event: 2 Header: 8039bd40 => After the 
referencing by handle
(ex/init.c:588) Refcount of New Event: 1 => After the ObDeRef
(ob/object.c:877) ObpDeleteObject(Header 8039bd58) => During Ntclose
(ob/object.c:899) Clearing name => The 0x28 block is freed.
(ob/object.c:925) Freeing header at :8039bd40 => The 0x50 block is freed
(ex/init.c:592) Refcount of New Event: cccccccc => After the NT Close. 
The header has been de-allocated

So no leaks on this path =(.
