True.  On the other hand, prefixing SEAMCALL_ over and over is tedious and adds
a lot of noise.  What if we drop SEAMCALL_ from the #defines?  The prefix made
sense when there was no additional namespace, e.g. instead of having a bare
TDCREATE, but that's mostly a non-issue now that all the SEAMCALLs are namespaced
with TDH_.
