Issue

I tried to upgrade werkzeug, urllib3, botocore, and boto3 and the resolver appears to have hanged.

poetry add werkzeug=^2 urllib3=^2 botocore=^1 boto3=^1

Amazon for whatever reason publish hundreds and thousands of releases of packages like boto3. If the solver takes an unlucky turn such that it hits a dead end not compatible with any boto3 release, it can take a long time to work through those hundreds and thousands of releases and realise that it is in fact in such a dead end.

Provide tighter bounds - then poetry can spot the dead-end more quickly.

Thanks @dimbleby !

I understand the problem here, and the workaround works well enough, but intuitively it seems a bit silly that poetry goes back into the vast abyss of botocore releases looking for an older version of the package to support a newer version of urllib3. If two versions conflict, wouldn't it make more sense to rollback the version of the more recent package?
