ULE returned to its "experimental" state
An internal discussion happened in -developers@ has finally decided that we put ULE scheduler back to the “experimental” state, in order to reduce the number of reports about crashes and other bad things for it.
Currently the fact that ULE is not being actively maintained is the cause of this change. We hope that we can find someone who has interest on it. Additionally, it is worthy to have a look at David Xu’s new “CORE” scheduler (a ULE fork, using Linux’s algorithm).
Note that ULE is still provided in NOTES so we can make sure that we do not break it badly.
