[GiNaC-list] is ginac thread safe for this case?

will ginac be thread safe for this case? 1) threads access diferent expressions which are independant 2) each thread will increase the expression its working in.. for example thread1...expression1 += x+y thread2.... expression2 += 2*x.... and so on. 2) no function evaluation is done never. 3) however, all expressions share the same global symbols ( eg, expressions made of global symbols x and y ). 4) threads access the same common matrix of expressions, but two threads will never access the same cell. i'am testing at the moment, and is working but in the long run i am not sure if problems will arise. any information, welcome. thanks in advance.
