PostgreSQL 9.0.2 hangs during shutdown on Windows (Win32)

Hello,

I am using PostgreSQL 9.0.2-1 (specifically the pre-compiled ZIP distribution
for Win32, postgresql-9.0.2-1-windows-binaries.zip, from EnterpriseDB
http://www.enterprisedb.com/postgresql-902-binaries-win32?ls=Crossover&type=Crossover)

The Host is an Intel x86 (Core2Duo) machine running Windows XP SP3 (32-bit).

When I try to shut down the database, it always hangs. Even if I simply start
the DB and then issue a shutdown (with no connections being made and no SQL
executed in between) the DB still hangs. I appreciate any info on what to do to
resolve this.

I have increased the log level to DEBUG5 (log_min_messages and
log_min_error_statement) and the output of the server is:

------------------------- START DEBUG OUTPUT
LOG: database system is ready to accept connections

===> ...Message above repeated several times

DEBUG: mapped win32 error code 2 to 2

===> This is where I immediately try a clean shutdown:
