GPT partition type (GUID) for (g)journal provider partition

[Carl]

I am using GPT for disk layout and I wish to use a dedicated partition 
for a gjournal journal provider rather than combining the data and 
journal into the same provider/partition. The question is this: What 
partition type (GUID) do I use for the journal partition?

The gpart(8) man page lists a number of symbolic names for different 
FreeBSD partition types, but none seem appropriate for the task.

For those that wonder, my reason for separating data and journal is that 
I am hoping to make up a little bit of the tremendous performance hit 
that gjournal causes by locating a journal provider in the fastest 
region of the disk even though its corresponding data provider must 
necessarily be located in the slower region of the disk. Is there a flaw 
in that thinking?
