there should be no issues with spawning extra threads using pthread_create in
your application. Can you provide a few more specifics and perhaps snippets of
code which exhibit the problem. For example, when spawning the threads before
init and remote launch - can you clarify in what way it is "not proceding"? Does
it do nothing, does it hang, does it crash etc.? Similarly, putting the
pthread later, where exactly does it wait? Does gdb show anything of interest,
or show more specifics as to what the thread is waiting on?
