So there is no way to avoid disk memory usage?
It's not good in terms of performance. But also since I may have many calls from clients on the server will not they race for the same tmp file?
Also, say if the process is interrupted by some reason in the middle the tmp file will never be removed.
Re^2: Question about Parallel::ForkManager
I didn't realized it used the disk. Pipes could be used, so I'm curious why it uses the disk. (Ah yes, using pipes would prevent the parent from doing other work while the children are running. This is usually not a problem, but it would break P::FM's interface to support this.)
There won't be a race condition. It surely defends against that using the process id in the file name.
