Hm, so you want druntime to execute an arbitrary number of functions on thread
creation and termination, each of which could throw an exception?  Yuck :-)  I
guess the functions could be required to be nothrow, but it still seems like a
problem waiting to happen.  I could be convinced to make the change, but
someone would have to present a compelling case for it.
