Re: [PATCH 0/4] Fix file locking with retry and timeout on Windows

> The first patch is the same that I posted earlier. It fixes a build
> failure on Windows on master due to missing random/srandom.
> 
> The remaining 3 patches replace the select() invocation that waits
> for a short time period by the version with poll() that we already
> use in help.c. This is necessary because a select() call where all
> three sets of file descriptors are empty is not supported on Windows.
