Bruce Evans (brucee@runxtsa.runx.oz.au) points out a BAD bug in my shared
text implementation.  A task being ptraced needs to have sharing disabled
or else you will clobber all other incarnations of that program.

Rather than implement a patch kit for my version, I am going to wait.
Bruce is testing a different version of shared text submitted by another
person and this version will not have that problem.  My advice (temporarily)
would be to ensure you make a private copy of a program being debugged
or better yet, remove my shared text code altogether (safer and more secure)
and wait.

Sorry for any problems this may have caused you all.  Hope Bruce gets his
out soon  :-).
