Hello this patch is significantly reduced original patch. It doesn't propose a simple allocator - just eliminate a high memory usage for ispell dictionary.
without this patch the ispell dictionary takes 55MB for tsearch2 context and 27MB in temp context. With this patch it takes "only" 25MB tsearch2 context and 19MB in temp context - its for Czech dictionary and UTF8 encoding. The patch is litlle bit ugly - it was reason, why I proposed a simple allocator, but it reduce a memory usage on 53% - the startup is better from 620 to 560 ms ~ 10% faster. little bit strange is repeated time - it goes down from 18ms to 5ms.
