I've seen this too, under 3.1 and 4.0.  I think Ultrix gets upset if
you change the sticky bit on an image which is already in the text
table--either a currently running image, or an image which had been
run recently and is still in the cache.

I thought the BSD documentation had some procedure which somehow
forces the image to be flushed from the text table--but I don't have
the docs handy to check it.
