Unless you are spawning lots of threads and at arbitrary times, this is
unlikely to be much of a problem. If it is, you likely should use a thread
pool instead.

Lastly, if you absolutely must, it is possible to spawn a thread using
methods other than D's built-in thread-spawning functions, and those would
not have their static constructors run. On the downside, you lose any
guarantees the compiler could give you, as just about anything that is not
a local variable is in TLS.
