You are right, looping through above shell script 10000 times is an enormous waste of resources and time. It creates 20000 processes for 2 commands to be run 10000 times. How about doing it in one command, leaving the looping to it? If $5 can have ONLY the values "X" and "Y", try
Should there be other values in $5 for which $2 should not be modified, try

af_abort
af_transact(3) Attribute Filesystem (AtFS) af_transact(3)NAME
af_transaction, af_commit, af_abort - a simple transaction mechanism for AtFS
SYNOPSIS
#include <atfs.h>
int af_transaction (void)
int af_commit (void)
int af_abort (void)
DESCRIPTION
These functions implement a simple transaction mechanism for AtFS. A transaction starts with calling af_transaction. All changes to exist-
ing ASOs performed hereafter have no immediate permanent effect. They rather get into effect, when the transaction is ended. Calling
af_commit ends the transactions and causes all changes to be saved to disk. af_abort aborts the transaction without saving the changes.
These will then be discarded.
Only modification of the state of existing source ASOs will be deferred. Creation or deletion of ASOs have immediate effect, regardless if
a transaction is in effect or not. Additionally, all operations on derived ASOs (all operations on the derived object cache) are not
affected by the transaction.
All archive files that are to be changed when the transaction is finished are locked until the end of the transaction. The lock prevents
all other applications to perform any modifications on the archive file. You should make sure, that ending a transaction should never be
dependent on the successful termination of another application (deadlock danger).
DIAGNOSTICS
Upon error, -1 is returned and af_errno is set to the corresponding error number.
BUGS
Changes to the contents of busy versions have immediate effect.
