in thread Buffered IO and un-intended slurping

My first thought was "how do I seek() on a scalar?" Buy you mention "opened that scalar as a ram-file" which seems to imply there is a way to do just that
How about a pointer to the method?

It is always better to have seen your target for yourself, rather than depend upon someone else's description.

    See open for details: 

    open my $fhFile, '<', 'theFile' or die $!;
my $slurpedFile;
{
    local $/;
    $slurpedFile = <$fhFile>;
}
close $fhFile;

## Supplying a reference to a scalar as the filename
## initiates the opening of a ram file.
open my $fhRam, '<', \$slurpedFile or die $!;

## Now file operations on $fhRam will read from the slurped scalar
my $firstLine = <$fhRam>;
...
