The problem is because env variable USER is not defined
on Mac, or at least for CGI. As a result a folder /tmp/j-0
is created first under user "www" and then for user
"youruser" it has no writing permissions.
Since for offline execution of jconsole break is not
used at all, it is possible to resolve this issue by
ignoring the error (::]) in setbreak, system/main/break.ijs:
({.a.) (1!:12) ::] fn;0 NB. 12 not 2
(9!:47) ::] fn
