Why shouldn't the thread of execution and scheduling time be provided by

Short answer: because then the provider could terminate the schedule
while the thread was executing within a critical region within the
server.
Game Over.
Hm. This is a serious problem. But sth. makes me feel it would be nice
to make the caller pay. But you're right, we want the caller to be
allowed to remove the thread or no longer pay for the scheduling.
Just out of curiousity:
Do you think it is possible to fully make the caller pay? I see two
ways: the one way is to design every server without such critical
regions (what's impossible, IMHO), or the server would need some more
promises... Maybye it was possible to grant the thread of execution and
make sure the caller cannot stop paying within such a critical region...
