// which in turn can have unwanted effects (see
// <https://bugs.freedesktop.org/show_bug.cgi?id=50603> "Unable to update
// LibreOffice without resetting user profile"). But closing fds in
// restartOnMac before calling exec does not work, as additional threads
// might still be running then, wich can still use those fds and cause
// crashes. Therefore, the simples solution is to close fds at process
// start (as early as possible, so that no other threads have been created
// yet that might already have opened some fds); this is done for all kinds
// of processes here, not just soffice, but hopefully none of our processes
// rely on being spawned with certain fds already open. Unfortunately, Mac
// OS X appears to have no better interface to close all fds (like
// closefrom):
