Feature Request

Hi!

Just tried to install Pytorch in my very first Poetry project and some of the experience left me guessing what was actually happening on my PC.

When installing a larger wheel (I believe for Pytorch it is in 500-700MB range) in a brand new environment, developers are presented with incredibly long dependency resolution times.

Resolving dependencies... (115.8s)

After that follows a package installation phase, that takes a bit of time as well (it seems there's some internet activity is happening during this phase as well), but specifying -vvv does not show anything other than:

  - Installing torch (1.0.1.post2)

Would be great to add a bit more transparency in what's actually happening when installing those larger packages.

This sort-of relates to how filelock can get into a deadlock'd state depending on the cache; if you don't know about the progress for the big dependency, it may be ambiguous if you are deadlocked vs just waiting for a big download.
