NHF, but the word "user" is overloaded in this sentence. I took "user code" to
mean "code produced by the user" (i.e. the programmer). I mean, I was surprised
to see something like ras(9) implemented, so I took this sentence to mean: the
user (= programmer) can create his own restartable sequences. (and the rest of
the manpage documents how...)
IMHO, putting "user-level" instead of "user" would be much more explicit.
Anyway, thanks for clarifying the issue.
