This x25 pre-dated the current setup where the mtime of the lock file is refreshed every
stale_age/2
seconds, so can be reduced.Regarding the cache pidlock, this means that different machines sharing a depot will now wait for 50 seconds rather than 4 minutes, given that they cannot do the faster 10 seconds stale assessment because they cannot check whether the process still exists.
Also include the pidfile path in the log message, so if the user wants to, they can
rm
the file and override the lock.Pkg counterpart JuliaLang/Pkg.jl#3654
