Hi,

 I finally found the cause of the 3.5.7 slowness. It was introduced by 
some safety checks to avoid crashes in the parser. Unfortunately this 
checks made the parser VERY slow, so no wonder people seeing several 
seconds delays with some bigger documents. 
 I changed the checks, while still keeping them. The result is 
impressive, my big test document (700KB, 12000 lines) parses in about 
350ms compared to the 3.5.7 version where the same operation took 
11-14seconds(!). Switching away from this document to an empty one took 
no less than 48-50seconds, while now it is around 60ms.
 Also the checks were not completely correct, so 3.5.7 could still 
crash. Now 3.5.8 not only that it should be stable, but it should be 
also almost as fast as the previous 3.5.x versions, prior to 3.5.7.
 3.5.8 will be tagged on Sunday, but I ask those who are used to compile 
from source to download the latest version from the Subversion 
repository[1] and test it. It includes some other fixes as well, and 
may include some more as the week progresses. :)
