[pve-devel] [PATCH 2/2] monitor diskio with qmp command

[Alexandre DERUMIER]

Isn't more simple to use something like this ?

http://search.cpan.org/~nilsonsfj/subs-parallel-0.08/lib/subs/parallel.pm
or
http://search.cpan.org/~odigity/Parallel-Simple-0.01/lib/Parallel/Simple.pm

(But maybe they use some king of threads or fork ?)

They is no way to do real threading with perl ?

I guess we can use IO::Multiplex for that:
