persisting gpg-agent keeps cmd batch windows open

[LigH-de]

Please excuse if the location for this issue is wrong; but it seemed to be the most specific project's tracker to me.

When pacman-key is used in a Windows batch, a process of pgp-agent spawns. According to IRC #gnupg, this is automatic and can't be disabled in a gpg.conf anymore in GnuPG v2.

As long as this process is alive, the cmd window running the batch file (specifically, MABS) will not close when the batch finishes.

I tried to kill this agent at the end of the batch, using the following command:

gpg-connect-agent -q killagent /bye

This prints as result:

OK connection closed

but the process 'gpg-agent.exe' persists. Current workaround:

taskkill /IM gpg-agent.exe /f

at the end of the batch.

May this be an MSYS2 or more generally GnuPG Windows build specific issue in a way that gpg-connect-agent tries to kill the gpg-agent process with a method that doesn't work reliably in Windows?

This affects us on Travis CI, and seems to have changed very recently: XboxDev/nxdk#218

Does anybody know when / where / why this changed?
Can we remove the taskkill altogether?
