<function>umask</function> without arguments simply returns the

Avoid using this function in multithreaded webservers. Better change the file
permissions with <function>chmod</function> after creating the file. Using
<function>umask</function> can lead to unexspected behavior of concurrently
running scripts and the webserver itsself because they all use the same umask.
