The number of open file descriptors reported by lsof is unreliable because it depends on whether the parent process (the test) closed the file descriptors it passed into the child process (lsof) before lsof runs. Reading /proc/self/fd directly on Linux appears to be much more reliable and still detects any file descriptor leaks originating from attempting to run an executable that cannot be found (issue #5071). If /proc/self/fd is not available (e.g. on Darwin) then we fall back to lsof and tolerate small differences in open file descriptor counts. Fixes #19243.
