The literature gives four primary arguments for the supremacy of events:

Inexpensive synchronization due to cooperative multitasking
In working with ～
In working with these systems, we realized that the properties above are not restricted.
Ultimately
Ultimately, our experience led us to conclude that event-based programming is the wrong choice.

that (1) ～ that (2)
We believe that (1) threads provide a more natural abstraction for high-concurrency servers, and that (2) small improvements to compilers and thread runtime system can eliminate the historical reason to use events.
