the current python code uses 32bit filesystem funcs which can lead to random failures on some filesystems. please add AC_SYS_LARGEFILE to the configure after the call to AC_USE_SYSTEM_EXTENSIONS to fix.
Could you provide some article explaining why? Out of pure curiosity, since python-exec is never going to read more than ~50 bytes out of a file.
please see the blocking bug. it isn't just about read/write; stat fails too.
