The original code was ported from the C# module. It looks like it
tried to avoid reading TLS data by using a shared counter. However,
without also synchronizing on the counter check (or using atomics)
the code is racy. While the races might be benign (the thread that
sets the exception also increments the counter, so when there is
actually an exception, the visible value will always be non-zero
even if it is outdated), they are still undefined behavior,
strictly speaking. Additionally, just using TLS isn't expensive
either.
This was suggested by wsfulton on the mailing list in order to bring the D module in line with the C# one, the naming scheme of which is intended to be language-independent.

A C++ class called "Exception" could shadow the built-in one before, leading to compilation errors in the exception handling code.

It is still a bit rough around some edges, particularly with regard to multi-threading and operator overloading, and there are some documentation bits missing, but it should be fine for basic use.
The test-suite should build and run fine with the current versions of DMD, LDC and Tango (at least) on Linux x86_64 and Mac OS X 10.6.
