"As a non-expert in hard real-time systems, the last sentence strikes
me as very strange. There are well-known GC algorithms that guarantee
hard real-time bounds, as well as reasonable (linear) space bounds.
Henry is the inventor of one."


During the design of Ada 95, it became abundantly clear that this view
is NOT shared by most experienced practioners in the real time field.
There are many "well known algorithms" in CS that are not yet ready
for actual deployment in real systems!


Yes, there are some counter-examples, including a couple of projects I
have been involved in, but they are the exception, not general
practice, in the real time field.
