Re: temporary disable thread switching using pthreads

There is no problem with SMP:

"DosEnterCritSec causes other threads in the process to block themselves

Really? What happens when any other thread holds a library lock
when it is stopped?

However, since there is no way to suspend a thread using pthreads, I
cannot implement it this way.

Nope, and there are good reasons why suspending threads isn't possible.

Unfortunately it is not always that obvious what kind of data is
protected by a critical section which is not directly related to any
data. I think I have to do some more redesign. :-/

If it's just data to be protected, a lock would suffice.
