The devil is in the details. There is a discussion in authorized services. Briefly, for a type 1 SVC, you suspend the current RB, schedule an SRB or whatever, and ultimately exit normally. When you exit, the suspension takes effect.

(was: Type 1 SVCs) Thanks, Seymour, for the info about type-6s. WRT GUPI, like most other ISVs, I use them when I can, and accept the occasional recoding obligations when I can't. My real question is... What happens when a type-1 SVC SUSPENDs? (Or for that matter, when any other locked or disabled environment SUSPENDs?)
