I have "hit" this "same" problem,
at Debian squeeze and nvi version 1.81.6-8.1 :
Using nview opens the file readonly but then re-opens it read/write,
as seen with commands:
echo abc > txt
strace -oout nview txt # use :q to quit
grep txt out # shows (amongst other things):
open("txt", O_RDONLY|O_LARGEFILE) = 4
open("txt", O_RDWR) = 4
(which is the same sequence that nvi would do).
This causes execution of various, e.g. CGI, scripts fail while the owner
is just viewing the source.
Cheers, Paul
