Two sequential calls to _thread_Enable_dispatch() ?!

Hi all,

Please look to the mqueueopen.c file.

Why there are 2 sequential calls to _thread_Enable_dispatch() function in the mq_open() POSIX.4 primitive?

Are they necessary? Does one call to _thread_Enable_dispatch() is not enough?

If there is configured extensions, each call to _thread_Enable_dispatch() will execute the exensions. Thus we are delaying the execution time of the mq_open() primitive, right?

Sorry, I am confused...

Can you help me?

Many thanks,
