Summary: 0000650: FIXED: two race conditions in initializer of HPC ALGLIB for C#
Description: Both race conditions were noticed rarely and only under very heavy load, when ALGLIB functions were called from multiple simultaneously started threads.

First race condition appeared during LoadALGLIBFunctions() call - globally accessible hAlglibDL variable was set before initialization of external native DLL was done.

Second race condition was found in addsearchpath() and resulted in out-of-bounds exception during initialization.
