The _Inline/build directory usually gets cleaned up, but not for notdef.pl

notdef.pl also NAME's the module, so its name doesn't change, but def.pl doesn't NAME the module, so a name is derived from the filename (def.pl) and the md5 sum of the c-source code 

$ cat _Inline\lib\auto\def_pl_4ff5\def_pl_4ff5.inl

Now, can two copies of notdef.pl run simultaneously? Lets see

First cleanup  $ rm -rfv _Inline

And one copy will trip over the other and die , the other will continue normally 

$ perl -le " system 1, $^X, q,notdef.pl, for 1,2 "

Now I'm not sure what scenario davido is talking about in the OP, but I hope this helps

FWIW, def.pl/notdef.pl are derived from XS: returning a 64-bit unsigned int?/Re: Inline::C with multiple *.c
