Has D's builtin TLS been optimized in the past 6 months to year? I had
benchmarked it awhile back when optimizing some code that I wrote and

now __gshared). Now, at least on Windows, it seems that there is no
discernible difference and if anything, TLS is slightly faster than
__gshared.
What's changed?
I was under the impression that TLS should be faster due to absence of
synchronization.
__gshared doesn't have any locks/barriers associated with them.
TLS should be slightly slower due to an additional indirection, but I
don't think it would be noticeable.
