Actually, it's not the global variable that causes the problem, but the bad
design of the DB class. The problem would be the same if he passed the DB
object as a parameter to the ctor - however, if the DB class would be
capable of handling concurrent queries (most likely by letting ::query()
return a result object), the problem wouldn't occur even with a global
variable.
So - yes, the global variable is a desease... but not the one the symptom
is pointing to. :)
