Yes, GC pauses get annoying when the heap gets large. This can lead to timeouts on the client side.
FWIW, we've talked in the past about GC and Web serving in general (not specific to the Racket Web Server; I was thinking of my SCGI library at the time).
Separate from any changes from GC research, if GC became a problem for my long-running Web app processes, there are options with the existing Racket version, including scheduling forces of GC cycles to when we think the process would otherwise be idle, making forced GC be part of load-balancing, and even periodically replacing a long-running process with a fresh one.
That last one would not apply if you're talking about keeping Web serving continuations in-core, of course, except as part of some smart load-balancing solution.
