843bd8e1d5 kernel/tasks: fix logical bug check_timers()
Only pop tasks from timer queue if their deadline is reached, this
was most likely a typo.

8054c36f26 gdb-scripts: backtrace and context switching for tasks
These new commands allow to show backtraces of any HermitCore task as
well as completely switching the current context. This way, you can
inspect each task as if it were running, which hasn't been possible
until now, because neither GDB nor Qemu have knowledge about the task
structure of HermitCore.

5a0d265e1a add dirty hack to reduce the startup latency
Qemu starts not fast enough. Consequently, we loose the first SYN
packet. But the timeout to retry the connection is per default too high.
I am not able to define the timeout value. I could only define the
number of retries.

=> add a sleep to wait for qemu
