<para arch="i386,ia64,pc98">An ehci driver has been added; it supports

|
|
controllers.</para>
|

<para>A minor bug in the permissions handling of
|

<filename>/dev/tty</filename> has been fixed. As a result,
|

&man.ssh.1; can now be used after &man.su.1;.</para>

<para>A bug that caused &man.fstat.2; to return

<para>A second process scheduler, designed to be a general purpose

scheduler with many SMP benefits, has been added to the scheduler

framework. Exactly one scheduler must be specified in a kernel

<para>&man.pam.ssh.8; has been rewritten. One side effect of the

each session to the agent started by the first session.</para>

<para>A 1:1 threading package (where for every pthread in an

Under this model, the kernel handles all thread scheduling

KSE code, and is a restricted case of the M:N threading work

still in progress. The <filename>libthr</filename> library

implementing the userland portion of this functionality is a

drop-in replacement for the <filename>libc_r</filename> library.
