Subject: [9fans] stack reclamation on Unix using clone, rfork_thread, etc.
Date: Fri,  4 Jun 2004 09:39:42 -0500	[thread overview]
Message-ID: <ee9e417a04060407397709613f@mail.gmail.com> (raw)

Anyone have any idea how one is supposed to arrange
to free the stack on which a shared-memory proc is 
running?

In my current implementation, I have a routine called
stackalloc() that keeps a list of all stacks ever allocated
along with the pids they were allocated for, and every Nth
time it gets called, it scans the list freeing the stacks that
correspond to processes that no longer exist.

Damn TLB-friendly operating systems.
