Semaphores on W2K

From the alert log on an otherwise problem-free 9.0.4 infrastructure V9.0.1.5.1 database, starting up after an OS restart:

alter database mount exclusive
Thu May 27 10:15:34 2004

ORA-09341: scumnt: unable to mount database
OSD-04400: unable to acquire internal semaphore for process
O/S-Error: (OS 997) Overlapped I/O operation is in progress.

Thu May 27 10:15:39 2004
Successful mount of redo thread 1, with mount id 2130186692. Thu May 27 10:15:39 2004
Database mounted in Exclusive Mode.
Completed: alter database mount exclusive Thu May 27 10:15:39 2004

The services listing of this db was stuck at "starting" and I could connect as sysdba in sqlplus in a dos box, but couldn't shutdown.

Would someone be so kind as to explain semaphores on Windows?

http://metalink.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=NOT&p_id=176354.1 doesn't exactly explain what the problem is, although I could guess a timing issue starting up the listener.
