| 22:15 | Merge from threading. thread_fork is now gone. thread_spawn is now the exclusive way to create a new thread. Thread state is no longer stored on the heap, each thread gets its own segment in kernel address space. A part for thread management state, and the runtime stack, with a guard page in between to protect against overflows. fork is now implemented in terms of thread spawn, and jumping to user space in the new thread using a modified copy of the trap frame from the original fork system call. check-in: ee32999f45 user: csmith tags: trunk | |
