CURRENT is no longer going to support KSE threaded applications. As
mentioned in UPDATING the following libmap.conf should work along with
compat libs for old dynamically linked libraries:

libpthread.so.1 libthr.so.1
libpthread.so.2 libthr.so.2
libkse.so.3 libthr.so.3

Statically linked binaries will no longer work. We're still investigating
whether 5.x binaries may have trouble due to problems in the 5.x libthr.
If this is the case we will make a special build of libthr to include in
compat5x.

Thanks,
Jeff

Removed files:

Log:
Remove kernel support for M:N threading.

While the KSE project was quite successful in bringing threading to
FreeBSD, the M:N approach taken by the kse library was never developed
to its full potential. Backwards compatibility will be provided via
libmap.conf for dynamically linked binaries and static binaries will
be broken.
