I'd like to see a standard response on the website along these lines.
Something like:

FAQ:
Q.Isn't GC slow and non-deterministic?
A. Yes, but *all* dynamic memory management is slow and 
non-deterministic. If you talk to the people who actually do real time 
software, they don't use malloc/free precisely because they are not 
deterministic. They preallocate all data.
However, the use of GC instead of malloc enables advanced language 
constructs (especially, more powerful array syntax), which greatly 
reduce the number of memory allocations which need to be made.
