	// Disable any ssh connection pooling by Git.
	// If a Git subprocess forks a child into the background to cache a new connection,
	// that child keeps stdout/stderr open. After the Git subprocess exits,
	// os/exec expects to be able to read from the stdout/stderr pipe

	// on binaries that we are going to run and then delete.
	// There's no point in doing work on such a binary.
	// Worse, opening the binary for write here makes it
	// essentially impossible to safely fork+exec due to a fundamental
	// incompatibility between ETXTBSY and threads on modern Unix systems.
	// See golang.org/issue/22220.
	// We still call updateBuildID to update a.buildID, which is important
