In this context it's not necessary to use thread static variable.
Harbour gives full read synchronization in accessing complex variables
so it's enough to use:
STATIC s_bBreak := { |oErr| Break( oErr ) }
It's the most efficient way because we eliminate creating new code block
each time BEGIN SEQUENCE WITH ... is used. Anyhow the overhead caused
by creating new codeblock is very small so it should bot be big problem
and above improvement is usable only if BEGIN SEQUENCE WITH ... is called
millions times in some loop.
