And finally, I've generated liblzma bindings using bcd, adjusted them
for D2,

(sorry about the httpd treating .d as application/octet-stream) - and
Fixed now (the httpd.)
then made a small threaded .xz compression hack to try out D2,
http://people.freebsd.org/~nox/tmp/d/xzj.d
This is very much a WIP but can already be used to compress
files or stdin to another file or stdout (so it can be used in
pipes and with tar's --use-compress-program), using all cores.
Binaries at:
http://people.freebsd.org/~nox/tmp/d/freebsd8/xzj
http://people.freebsd.org/~nox/tmp/d/linux/xzj
(both i386 of course) Run with -h for a small usage message
and see the source for more info.
Comments are welcome, also if anyone wants to test/port it to
non-FreeBSD/Linux and/or check if the lzma bindings are OK...
Also, should I submit the bindings somewhere? I checked the
struct sizes and they matched:
http://people.freebsd.org/~nox/tmp/d/lzmastructsizes-c.c
http://people.freebsd.org/~nox/tmp/d/lzmastructsizes.d
These are direct C bindings only tho i.e. I did not make a wrapper
class like std.zlib...
Ok so that's it for now, cheers,

PS: I've meanwhile found another WIP threaded .xz compressor written
in C, but it is specific to tarfiles (it even indexes them and can
extract a single file quickly), and it uses a private branch(?)
of liblzma:
http://github.com/vasi/pixz
http://github.com/vinzenz/liblzma
..and turns out pixz is not really using a private branch of liblzma
but just an old version of it (that still has lzma_index_init() taking
two args and that also still has lzma_index_record().)
