Answer 1

It needs to revert the actions it did, so this can take a long time. If it is an INNODB database, you can for instance look at this question: https://dba.stackexchange.com/questions/5654/internal-reason-for-killing-process-taking-up-long-time-in-mysql

So in the end: you need to wait for it to be eliminated

Answer 2

In my case, my /var partition was full, where the MySQL binlogs are written. Once I freed some disk space, the killed connections immediately went away.
