please support parallel operation

[Seth Arnold]

Hello, please consider supporting multiple package install processes simultaneously, similar to make's -j command line option.

Computers are getting more processors rather than faster processors at this point, and this trend is likely to continue.

This is a companion to Bug #1584299 which I filed for dpkg and apt. It only seemed fair to suggest the same of snapd though the need may be less drastic.

Thanks

Installing a package is not a CPU-intensive process; it's an IO-intensive one.

Per conversation on IRC:

<niemeyer> I think it can be closed
18:44:34 snapd indeed operates closer to make -j than it does to apt or deb in that regard
<niemeyer> Those really serialize all steps of the installation, while snapd goes wild and only rejects known conflicts as you pointed out pedronis
<niemeyer> make -j also doesn't parallelize _everything_ either.. just the things it knows are independent.. so vaguely resembling snapd's behavior indeed
