History
John Baldwin bdd64116b0 Always clear TDB_USERWR before fetching system call arguments. The 
TDB_USERWR flag may still be set after a debugger detaches from a
process via PT_DETACH.  Previously the flag would never be cleared
forcing a double fetch of the system call arguments for each system
call.  Note that the flag cannot be cleared at PT_DETACH time in case
one of the threads in the process is currently stopped in
syscallenter() and the debugger has modified the arguments for that
pending system call before detaching.
