[User-mode-linux-devel] implementation questions

[lars b. <la...@no...>]

I have some questions about the implementation of uml:

1. Why is TIMER_VIRTUAL used instead of TIMER_REAL?

2. Why is SIGVTALRM blocked during a SIGSEGV?

3. Is the kernel protedted from user mode access, and if so, how?

(Perhaps the answers could be documented somewhere, in case
someone else is interested in the implementation.)
