This is curious Herb, but based on the Whidbey era doc
http://whidbey.msdn.microsoft.com/library/en-us/dllproc/base/setprocessworkingsetsizeex.asp
SE_INC_BASE_PRIORITY_NAME is the needed privilege
to use SetProcessWorkingSetSizeEx to increase either the minumum
or maximum WS size to greater than the then current values.
This privilege is in the GUI "Increase Scheduling Priority"
i.e. SeIncreaseBasePriorityPrivilege
So, to impact the time-slice results from the scheduler algorithm
one needs the "quota" priv, but to alter the mem allocation algorithms
one needs the "scheduling" priv.
Figures.
