that this is the case: sleep in an ioctl, and the entire process hangs until the ioctl returns.
which is probably what's happening in my case. i've got 4 threads spun off, and one thread reads what the other writes and vice versa. after writing, a thread goes off into an ioctl or a read where a tsleep() is executed. this would block the reader thread as well if libc_r were to be used, as is what i am using.
