Summary: sfcb deadlocks on nsHt initialization

Initial Comment:
The global variable nsHt in classProviderGz.c is initialized in getNsReg() with a simple
  if (nsHt==NULL) nsHt=buildClassRegisters();

This is not sufficient on fast multi-core systems. While one threads executes the "nsHt=buildClassRegisters();" part, another thread might reach the "if (nsHt==NULL)" part, resulting in buildClassRegisters being executed in two concurrent threads.
