since it seems you are using zexy anyhow, i'd suggest [fifop], which is 
a FIFO (with priorities; but you can safely ignore them is you don't 
need them).
for pure self-advertisment, there is also a [lifop], but you probably 
won't need that.

also there is [listfifo] in maxlib, (which apparently works on lists and 
has no priorities)

i am sure that these objects could be build somehow with the new [list] 
(but i haven't had the time yet to do so, frank ?)

this sounds like [speedlim] from iemlib2.
