This is a bug in the perl test case.
The error number 11 is EAGAIN, which means it needs to retry the
thread creation.
POSIX says:
~~~
[EAGAIN]
The system lacked the necessary resources to create another
thread, or the system-imposed limit on the total number of threads in
a process {PTHREAD_THREADS_MAX} would be exceeded.
~~~
There are several code paths during thread creation that may return
EAGAIN, and the testsuite should handle that.
Cheers,
Carlos.
