[mapserver-users] Making Mapserver Multithreaded

[Scott Shealy]

Frank can you also put a mutex on the parsing and evaluation  of the 
EXPRESSION Objects msEvalExpression(....)  ....(I havn't had a chance to look 
at the code yet)?

BTW I a slowly working on replacing the lexical anaylyzer and parser in 
mapserver so that they are thread safe. and we want have to use mutex to 
protect these critical sections of the code . Mutexes will cause scability(ie 
can't take advantage of SMP) and intreactity problems... For me this is  
particularly noticeable b/c in my maps I evaluate some really large 
EXPRESSIONS....
