It applies to shared libraries in general. I do get a segfault on exit when
trying to use std.parallelism in a shared library (linked dynamically with
druntime/phobos), which seems to be in accordance with Martin Nowak's
comments here: https://github.com/dlang/druntime/pull/593

It's not about tiny druntime, it's about its clear separation from Phobos
so that extensions built with different versions of Phobos can be safely
loaded together (there can't be two druntime GC running at the same time).

Now that is deep! In reality, though, most programming languages nowadays
are object-oriented with decent support for functional programming. It's
libraries and tooling that matter the most. E.g. nobody would give a damn
about Ruby nowadays if not for RoR. Or consider JS: it's the language of
the web, but it wasn't at all designed for its current usage, and
workarounds that are used are just mind-blowing.

These metrics show growing interest, but this interest apparently comes
mostly from busy people, who often address 'their own pain' with
undocumented/unorganized code which never makes it to d.announce. Students,
on the other hand, are interested also in proper documentation and testing.
