[svn] * src/lock.h,src/lock.c,src/noffle.c: Add lazy lock release. Only release
the lock and close the databases if (a) another process signals us
SIGUSR1 indicating it wants the lock, or (b) it is explicitly requested by
a call to new function Lock_syncDatabases(). When waiting for the lock,
SIGUSR1 the holding process every second. This is all an attempt to
minimise the number of times we need to close and open the database.
When (ha!) the database is replaced by something that can handle
multiple simultaneous writers (with appropriate locking) this won't
be necessary.

------------------------------------------------------------------------------- NOFFLE FAQ ------------------------------------------------------------------------------- Q: What is the difference between NOFFLE and leafnode? A: NOFFLE uses less resources (disk space and bandwidth). Downloading groups in overview mode is several times faster, because it uses the XOVER command instead of HEAD. In addition, there is the quasi-transparent mode, when online, which allows to browse through groups and cache everything without subscribing. NOFFLE is GPLed, leafnode isn't. ------------------------------------------------------------------------------- Q: I subscribe to groups, but get a "Retreiving failed" message for every requested article. A: Some news server do not allow retrieving articles by message-ID. You cannot use NOFFLE together with these servers presently. ------------------------------------------------------------------------------- Q: I changed the server in the config files, but the new groups do not appear. A: You should run 'noffle --query groups' again. If you want all old group information deleted, you should remove the file data/groupinfo.gdbm in the spool directory before. ------------------------------------------------------------------------------- Q: The Emacs news reader GNUS hangs while getting active list from server. A: This is a known phenomena and I believe that it is a bug with GNUS, because the log files show correct handling of client commands by noffle.
