I don't know Tcl internas but I hope the loader initializes everything
correctly on startup.  Clearing BSS is easy, but initializing DATAs
is complicated, as the loader must keep a copy of a fresh DATA
segment.  Then there is the signal issue and more things I don't want
to think about.  Probably easier to do a fork/exec.
