Initial Comment:
Solaris 2.7, 2 CPU machine

[belinda 14]--> gcc -v
Reading specs from
/usr/local/lib/gcc-lib/sparc-sun-solaris2.7/2.95.3/specs
gcc version 2.95.3 20010315 (release)

Tcl 8.4a3, built thus:

./configure\
	--enable-threads\
	--enable-shared\
	--enable-gcc\
	--prefix=/opt/tcl8.4a3

Thread package built thus:

./configure\
	--enable-gcc\
	--with-tcl=/opt/tcl8.4a3/lib\
	--enable-shared\
	--enable-threads\
	--prefix=/opt/tcl8.4a3

The attached tar file contains three small scripts. If
you run:

tclsh8.4 boss.tcl

You should be able to get it to do this:
