recovery test failures on hoverfly

I noticed that we are getting random failures [1][2][3] in the
recovery test on hoverfly. The failures are in 022_crash_temp_files
and 013_crash_restart. Both the tests failed due to same reason:

ack Broken pipe: write( 13, 'SELECT 1' ) at
/home/nm/src/build/IPC-Run-0.94/lib/IPC/Run/IO.pm line 558.

It seems the error happens in both the tests when after issuing a
KILL, we are trying to reconnect. Can we do anything for this?
