Regression? Can no longer restart inferior with record-replay

Hi,

It is no longer possible to restart the inferior when RecordReplay is enabled.

See below for a session.  The change was introduced in commit:
b3ccfe11d3b0fc84f8ccd4e4fa25b75d1dc71cfc "fix regressions with target-async"
It is both in the 7.8 branch and master but not in 7.7.1.

Am I right to think this is a regression or was this a conscious decision? 

Thanks
