- it makes sure the threads are spawned by kevent so they are independent
from the enviroment of the caller. This is important for all the ongoin
container work aswell as to avoid possible security issues.
- it reduced complexity for thread creation and stopping a lot and thus
eliminates various bugs crept in all over the place
(- we want to remove the kernel_thread export so people stop opencoding it
in new code)
Using Tomcat but need to do more? Need to support web services, security?
