Some important parts of the GO Network portal backend use this
approach. It has pluses and minuses, but it is clearly good
enough for 24/7 online systems.
If anyone wants to dig into models for concurrency, I recommend
this paper:
Hugh C. Lauer, Roger M. Needham: On the Duality of Operating
System Structures. Operating Systems Review 13(2): 3-19 (1979)
It arose out of hallway arguments over message-passing versus
monitor programming styles. They prove the two equivalent, then
go on to describe the flavor of each style. Very useful perspective.
