Thanks for reporting the problem. It's annoying that gzip must invoke

reasonably portable alternative
I 100% agree.
I am considering a different approach for lzip; adding a new option, say
'-y, --fsync', to call fsync when acting in-place. This provides safety
to those needing it without slowing down the work of everybody else.
Especially of those (de)compressing a lot of replaceable files in-place.
(Ddrescue provides the option '-y, --synchronous' because calling fsync
by default is too slow).
What do you think?
