Hi okl4.org,

I'm just curious, do you know why is it that every iguana's thread
(ig_timer, ig_serial,  ig_naming,  vmlinux)  has  000e0001 as its scheduler
and non of them is such thread, what is interesting is that such(000e0001
id) is given to the first thread created by a new added server, for example
if I ass a new server (servtest) and that server creates a new thread (with
thread_create_simple), it gives it the 000e0001 ID, meaning that such thread
will be (ig_timer, ig_serial,  ig_naming,  vmlinux, servtest, L_timer,
L_syscall) scheduler, (wombat threads are different since they use they are
created using the eas_create_thread function on which scheduler is
specified), anyways,  do you know why is that?

I'm working with OKL4-1.4.1.1 for ia32, here is some KDB output:
