You can patch base.php to not issue that directive.  Just make sure you've
allowed plenty of time in a worst-case scenario for imp - at least 45 seconds.

These can be addressed by allowing PHP to alter those vars:

safe_mode_allowed_env_vars = PHP_,LANGUAGE,LANG,TZ

You can make this a VHOST-specific directive with the php_admin style
directives, if you're extra paranoid.

You can get IMP working fine in Safe Mode - the only problem I wasn't able
to work out with Safe Mode is the spelling checker.
