Created attachment 141149 [details] [review] patch Cairo opens files without O_CLOEXEC. The attached patch fixes this in all places in the library only; I didn't change the utils etc. The "e" mode for fopen() is a GNU extension, and I don't know if it's supported more widely (or at least ignored on other platforms that don't support it), so I made it used only on GLIBC.
