Take into account intel-openmp for mutex?

[h-vetinari]

I was wondering if intel-openmp (from here) also should be handled by this mutex?

A while ago, I got the following clobber-warning:

ClobberWarning: This transaction has incompatible packages due to a shared path.
  packages: conda-forge/win-64::intel-openmp-2020.3-h57928b3_311, conda-forge/win-64::llvm-openmp-11.0.0-h74a9793_1
  path: 'library/bin/libiomp5md.dll'

I then removed llvm-openmp for windows, but that drops the openmp-compliance in windows from 4.5 to 2.0, and I don't know how severe the performance impact of that is.
