Are you saying that if we write new thread-safe virtual_chdir() and
virtual_getcwd() functions and substitute the ones existing in PHP things
won't work? I very much disagree with you.
Anyway, most places in PHP that open files use fopen-wrappers.c so they
will automatically work later on. If there are any places which don't use
them (there really shouldn't be very many if any at all), we will have
another function for them char *virtual_get_fullpath(char *filepath) which
will return the fullpath to a filepath.
