Yes and no. Everybody opening a file can specify a share mode, e.g.
"share for read", "share for write" or "exclusive access".

Depending on the share mode for other open handles to the same file,
the next open attempt will fail or succeed.

I don't know if LLVM/Clang or some other app on Ivan's system is
opening the files with exclusive access, but if it's Clang, maybe the
requested share mode could be lowered to read-only?
