Example 1: my test file with your finder.
--------------------------------------------------------------
MPlib finder: mpost.mp -> d:/context/tex/texmf/metapost/base/mpost.mp
MPlib finder: mpost.map -> 
MPlib finder: plain.mp -> d:/context/tex/texmf/metapost/base/plain.mp
t={
 ["log"]="This is MetaPost, Version 1.003 (INIMP)  23 APR 2008 07:51 
(mpost.mp(plain.mp\
Preloading the plain mem file, version 0.99)",

",
}
--------------------------------------------------------------
found = ""
no mpost.mem, no mpost.log

Example 2: my test file with your finder and ("wb" not "w")
--------------------------------------------------------------
MPlib finder: mpost.mp -> d:/context/tex/texmf/metapost/base/mpost.mp
MPlib finder: mpost.map -> 
MPlib finder: plain.mp -> d:/context/tex/texmf/metapost/base/plain.mp

mpost.mem gets written now
but no mpost.log
