In our previous episode, Sven Barth said:
Think what happens if those are simply "cloned".
Why shouldn't reference types work in threadvard records? As long as the
reference count mechanism does it's work correctly it should work.
Afaik because the ref count mechanism doesn't. The cloning process might be
done by the OS.
So you have a record with that points to an ansistring with ref count 1, and
then you create twenty threads, and you have 20 records that point to an
ansistring with refcount 1.
For the same reason, the content of the buffer is duplicated.
If e.g. you have 'blabla' in a threadvar filerec buffer, create a few
threads and flush them, you will have several times 'blabla' written
But Pierre and Sergei have done so much on TLS, that I don't know the
current situation.
After writing the mail you answered to this occured to me as well which
is why I wrote another mail directly after that ;)
But nevertheless thank you for explaining.

Sven
