In 2.8.1/Windows (32 bit), they return immediately, though the
stack-overflow case is about 13x slower.

Are you running under 64 bits? How long does a vanilla infinite
recursion take to fail on your machine? I get:
> system.time(for (i in 1:100) trySilent({fff <- function()fff(); fff()}))
user system elapsed
0.27 0.00 0.26
-s
