        <pre>The flaky failures seem to be around file redirects that look like this:

# RUN: echo "first-line" > %t1.out && echo "second-line" >> %t1.out

# RUN: FileCheck --check-prefix CHECK-AND < %t1.out %s

This affects both sequencing-0.txt and redirects.txt.

They have logs that look like this:

$ "echo" "first-line"

$ "echo" "second-line"

$ "FileCheck" "--check-prefix" "CHECK-AND"

"C:\src\llvm-project\llvm\utils\lit\tests\Inputs\shtest-shell\sequencing-0.txt"

# command stderr:

C:\src\llvm-project\llvm\utils\lit\tests\Inputs\shtest-shell\sequencing-0.txt:7:14:

error: expected string not found in input

# CHECK-AND: second-line

<stdin>:2:1: note: scanning from here

error: command failed with exit status: 1

There is some strange lack of synchronization here. The writes to %t1.out are

not observed when we open %t1.out for reading for input to FileCheck.</pre>
