I want to add that on some platforms ( like linux, SGI ) there is
a threadsafe X11. The current TTHREAD implementation supposed
that X11 is not thread safe. This means that if some thread creates
Canvas
or simple do printf statement the request to the main thread is send to
do the job

Due to CINT is not thread safe only the main thread can use CINT,
the other threads should be precompiled.

But there is no yet option for user defined threads.
