Yes, because AFAIK a semaphore do not have a concept of owner. [...] > > Actually I was reading about synchronization mechanism in Linux ans > Windows. So same case is applicable to mutex as well.

A sempahore which has ownership awareness is very close to mutex. May I suggest using Mutex instead of semaphore, unless absolutely necessary. Advantages - Easy to debug, once who takes the lock releases it etc etc. CMIIW.
