With gcc and gdb, at least, all you have to do is run the 'vtk' executable
from within the debugger.  I do this all the time, both with tcl and
python.

With gdb, you do

gdb /usr/local/bin/vtk   <or wherever vtk is>

then

run <name-of-tcl-script>

The easiest thing to do with an infinite loop is just <Control-C>
followed by a stack trace (i.e. the 'bt' command).  You can also
set breakpoints in the C++ code, though there are a couple extra
gdb commands required to tell gdb where the .so files are.

Unfortunately, I don't have much experience with any debuggers
except for gdb.
