Bhavbhuti,
I checked the code and it already have bugs in itself (sorry Nadya). ie:

if !used(m.tcAlias) ...

Is never a guarantee that table is not in use (Nadya remember alias might not be the same as tablename). Plus table might be in use with or w/o same alias name in another session. Code not looping sessions if I didn't miss it.

use (m.tcTable) again &tcMode in 0 alias (m.tcAlias)

Having tcMode as EXCLUSIVE doesn't guarantee you opened it in exclusive mode. It might be opened as shared and no error shows up (bug,feature?). ie:

use employee shared
use employee again exclusive in 0 alias e1
? Isexclusive('employee'), IsExclusive('e1')

"AGAIN" there is introducing an implicit logical error that you can't catch w/o checking.
