I'd prefer the static choice model - and I'd hide this in some
"task_cred_read_lock()" function anyway rather than have the users do
"mutex_lock_killable(&task->signal->cred_guard_mutex)" like they do

How nasty would it be to add the "upgrade" op? I took a quick look,
but that just made me go "Waiman would know" ;)
