Function unshare_unsafe 

pub unsafe fn unshare_unsafe(flags: UnshareFlags) -> Result<()>

unshare(flags)—Disassociate parts of the current thread’s execution context with other threads.

Safety

When using UnshareFlags::FILES, this function can cause one thread to be unable to use file descriptors created on a different thread. Callers must ensure that threads never observe file descriptors from unshared tables.
