when creating a semaphore using syscreateeventsem, the
the semaphore object gets the windows-default
permissions. which means, that only the user, who
created it, can access it.
if a rexx process which is started by another user,
tries to access the semaphore an error is returned and
program execution is interrupted.
1.) implement a feature to change the acl's of the
2.) reimplement the syscreateeventsem, so that the
semaphore object automatically has full access for
everyone (see sample).
