Subprocess_Quota

   Pine uses subprocesses to perform several of its tasks. As such,
   users without subprocess quota cannot do any of the following:

   o  use a customized printing command,

   o  view image or video attachments,

   o  use the spell checker, or

   o  use an alternate editor.

   A side effect of using subprocesses in Pine when you have a
   remote IMAP connection is that the connection might timeout while
   waiting for a subprocess to complete. This is especially likely
   when using an alternate editor to compose a message.
