Hi,
attaching to a container using attach_wait from python-lxc blocks all other
threads since it is not GIL-aware.
This can be a problem if you want to run a timer thread, which stops the
container after a certain timeout has occured.
I've provided a solution below:
diff --git a/src/python-lxc/lxc.c b/src/python-lxc/lxc.c
index 1bc977a..91c199f 100644
--- a/src/python-lxc/lxc.c
+++ b/src/python-lxc/lxc.c

if (wait) {
+ Py_BEGIN_ALLOW_THREADS
ret = lxc_wait_for_pid_status(pid);
+ Py_END_ALLOW_THREADS
/* handle case where attach fails */
if (WIFEXITED(ret) && WEXITSTATUS(ret) == 255)
ret = -1;
