Thank you for your quick answer.
I had discovered the ---disable-inotify option, but some users may have scripts they don't want to modify, so we'd prefer not to use it.
Thanks a lot anyway.

Best regards.

Since you took the time to identify the fix
I'm applying this in your name.
Please advise if you'd like a different email address.
Note one can work around the issue without a patch
for the moment by using the currently undocumented ---disable-inotify option.
