* bsd_mutex.cc (_msleep): Simplify event creation. Revert change from
2004-08-24. It should be unnecessary now.
* msg.cc (client_request_msg::serve): Release process critical
section as early as possible.
* sem.cc (client_request_sem::serve): Ditto.
* shm.cc (client_request_shm::serve): Ditto.
* process.cc: Use hold and release method calls instead of
EnterCriticalSection/LeaveCriticalSection calls throughout.
* process.h (_hold): Rename from hold. Take filename and linenumber
parameter for logging. Define matching hold macro.
(release): Ditto.
