So you're just taking BrowserUk's word for it?
No, but I do not have enough knowledge in the Windows operating system and the Perl implementation on it to make such a statement!
In this patch http://perl5.git.perl.org/perl.git/commitdiff/bee96257ad6e12bd0adacaeb3b40c32c5776b068?hp=2fbb14a0b50722f55cd2863203a1ea1a3c2133f7 I succeed to add some information on “Portability issues” to perlfunc. In perlfunc there is now very short information on some security issues, a link to perlport and in perlport a link to perlfork
I have later realized that this is not enough. For me it is very difficult to interpret the consequence of the information in perlfork.
I would like, already in perlfunc, to have more straightforward statements like:
“do not attempt to use fork & the windows signals emulation to try to port *nix idioms to windows; because you will be sadly let down”or
“If you want to write cross-platform code, you shouldn't use signals, full stop.”(The statements should of course be polished. I hope somebody with English as native language could help out.)
