popen() doesn't return false on non-existent file. Bug#9043 says that it is intentional, but probably it's not the expected behavior and should be noted in the manual.

if (popen("/i/dont/exist","r")) echo "OK";

results in "OK" (and no warning is issued).

Also applies to exec(), system() and backtick operator.
