[development] Kind of problem - long nodes

[Tamir Khason]

It's seemed to be a problem in Drupal core 4.7.2.
Long and frequently updatble nodes are cutted (include inside DB) up
to some countble value. According MySql reference, the maximum allowed
length of LONGTEXT columns depends on the configured maximum packet
size in the client/server protocol and available memory. So it might
be a chance that nodes will be cutted and content will be lost.
