If you search the web under 'threads', you will eventually find a
SunMicroSys location that has a number of examples of threaded code. One
of these examples a 'tgrep' which is a multi-threaded grep. It is used as
a testbed for different threading implementations.
This might be a good test for the people who want to put in kernel
threads. There is also a set of files there that convert POSIX threads to
Solaris threads.

*Introduction.
Tgrep is a multi-threaded version of grep. Tgrep supports all but the
-w (word search) options of the normal grep command, and a few options
that are only avaliable to tgrep. The real change from grep, is that
tgrep will recurse down through sub-directories and search all files
for the target string. Tgrep searches files like the following command:
