I've now verified that the uncontrolled appropriation of memory for my large
transformation is definitely associated with the use of pDomlette.  I
changed my script to use p- instead of c-Domlette, and got the same
unrestrained appetite I had seen in the 4xslt.bat driver.  Changing my
script back to use cDomlette restored the limited use of memory I had
originally seen.

Here is the code fragment I've been changing (I took it from some 4suite
code quite a while ago):

    from Ft.Lib import pDomlette
    BETA_DOMLETTE = 1#os.environ.get("BETA_DOMLETTE")
    if BETA_DOMLETTE and not validate_flag:
        from Ft.Lib import cDomlette
        g_readerClass = cDomlette.RawExpatReader
        reader = cDomlette.RawExpatReader()
    elif validate_flag:
        reader = pDomlette.SaxReader(validate=1)
    else:
        reader = pDomlette.PyExpatReader()

I just changed the 1 on the second line to a zero to use pDomlette.

Cheers,
