[Rd] Adding lock capabilities to parallel?

[Ivan Popivanov]

Hello,

Sometime ago I had to solve the problem of writing to common files from
parallel R processes. For the synchronization, I created a small package (
https://r-forge.r-project.org/projects/flock/) to perform a lock/unlock
between different processes. My feeling is that this is something that
belongs to the parallel package.

There is at least one other package (synchronicity -
http://cran.r-project.org/web/packages/synchronicity/index.html) providing
similar (and more) functionality.

Regards,
Ivan
