Threading is rather OS-specific, despite standards like POSIX.  So if
you're developing on Linux this is not an unreasonable question if you
want to use kernel threads.

There are a number of thread libraries which run in a single kernel
process and do their own scheduling (a kernel thread is scheduled by
the kernel) as well.  The coda-fs uses an implementation called LWP,
the docs are available at www.coda.cs.cmu.edu.  There are probably a
number of packages for Linux, look in your package list.

AFAIK most thread implementations allow you to solve all the problems
you mentioned.  The only real problem is "trouble" recovery; I presume
you need to catch all of the signals that can kill the process and
handle them.  And I seem to recall that some thread implementations,
including Linux, have the problem that you can't signal an individual
thread; signals go to all threads.  So you'd have to hack around that.

I can't help with the details, though.
