But those of us with the runtime disabled don't have TLS.
This is only true on DMD/OS X x86, where TLS is emulated in
druntime. On other platforms, TLS is implemented by the linker
and/or C runtime, so it works without druntime just fine.
TIL, thanks.
Regular thread-local module constructors (static this) of
course won't work without druntime support, as they are
mediated through ModuleInfo.

Sure.
This means TLS is here but uninitialized and eg. core.cpuid has
to be duplicated.
Fragmentation ensues.
