MCST e2k (Elbrus 2000) architecture has half native / half software support of most Intel/AMD SIMD
e.g. MMX/SSE/SSE2/SSE3/SSSE3/SSE4.1/SSE4.2/AES/AVX/AVX2 & 3DNow!/SSE4a/XOP/FMA4

E2K - this is VLIW/EPIC architecture, like Intel Itanium (IA-64) architecture.

This gives user visual feedback that the refresh is still pending, and
prevents people from clicking again and again thinking nothing is
