Relevant comment:

This is a really major break in the env program: it doesn't re-execute with the subcommand, instead it forks! So then terminating the env process keeps the subcommand running. This affects all scripts whose shebang uses /usr/bin/env.

Reproduced on commit 2ba3a33, there do not seem to have been more recent commits to env after that.
