I wonder about function calls when in streaming mode, where someone might not 
even realize they're in it.  Does lldb-server support QSaveRegisterState / 
QRestoreRegisterState around inferior function calls, or does lldb use the g/G 
packet (or write all the registers individually)?  g/G are probably going to 
fetch / write all the floating point registers and reset the mode if you did a 
function call while in streaming mode?
