Many thanks for looking into this!

I have previously also found memory leaks in connection with
emacsclient. Please see #1504 for a test case:


A major problem with such memory management issues is that they prevent
you from running longer automated test cases to track down other, often
unrelated, issues that sometimes take a long time to reproduce.

Therefore, thank you for your work in this direction!

All the best,
