if it is the second longword following symb_size that is non-zero, then
TC is using a (yet undocumented i guess) feature of TOS 1.4. If this
long has its lowest bit set, then when launching a process TOS will not
clear all of TPA, just the BSS area. If it is zero, then it will behave
as normal, ie. clear all of TPA including the BSS area of the process.
