As a side note, I discovered this week that the Objective-C runtime also
depends on knowing the size of a section to initialize itself properly. This is
for a section that contains all the protocol definitions aggregated together;
upon loading an image the list is traversed to 'fixup' the protocols...
The interesting point is that it does so without this begin,content,end section
trickery, so it doesn't matter if sections get reordered during linking, which
would be much more robust.
>From what I found out by digging in the source code, this involves calling
'getsectdatafromheader' (or 'getsectdatafromheader_64') which returns the size as part of
its last argument (see header "mach-o/getsect.h"). I'm not exactly sure how this
all works, but there's definitely a way to make it work because it does work for the
Objective-C runtime. Perhaps I should investigate a little more and send what I find on the
list for druntime.

If such works, then I'm all for using it to replace the current method.
