exec_test.go's init function uses os.NewFile(fd) + f.Stat as a portable
mechanism to determine if an FD is in use.
Unfortunately, the current use is racy: if an unused FD becomes used
between NewFile and f.Close, then we will unintentionally close an FD we
do not use.
We cannot simply drop Close, as the finalizer will close the FD. We
could hold all of the os.Files in a global for the lifetime of the
process, but the need for such a hack is indicative of the larger
problem: we should not create an os.File for an FD that we do not own.
Instead, the new fdtest.Exists provides a helper that performs the
equivalent of fstat(2) on each OS to determine if the FD is valid,
without using os.File.
We also reuse this helper on a variety of other tests that look at open
FDs.

Because any is an a alias, it is naively formatted as interface{} in
error messages. This is a source of verbosity and potential confusion.
We can improve the situation by looking for pointer equality with the
any type. To avoid churn in the importers, do this all at once across
the compiler, go/types, and go/internal/gcimporter. CL 364194 makes the
corresponding change in x/tools/go/internal/gcimporter, allowing the

the questions whether *P for a type parameter P has methods or

don't have methods.
