Agree.

We've seen problems with _socket before.

#2427 was caused by anaconda.
#2895 was caused by mixing 32bit vim and 64bit python.
#3580 was caused by incorrectly compiling vim.

They are different.
--with-python3interp=dynamic or export LD_FLAGS="-rdynamic" can not reslove.
The problem mentioned need to install deps-library ,re-configure and re-build python
