Summary0000589: Some files are not properly closed
DescriptionSome part of FreeCAD opens temporary files and does not properly close them. A long term running Python script which makes some FreeCAD API calls results always in the following error:

OSError: [Errno 24] Too many open files

Looking with `lsof` at the process shows *a lot* of open files like the following:

python2.6 14603 ms4py 612u REG 8,1 2930 1998969 /tmp/filezSyDlu (deleted)
python2.6 14603 ms4py 613u REG 8,1 2774 1998970 /tmp/file5H0Tos (deleted)

These files are obviously created with FileInfo::getTempFileName, but I couldn't track where the files are actually opened.

Platform: CAELinux 2011 (Ubuntu 10.04 64bit)
FreeCAD: 0.13, rev4972
TagsNo tags attached.

Same issue with freecad-daily (rev5070).

Is there a certain procedure to force this problem to appear?

It seems that the function mkstemp() already opens a tmp. file and there is a constant TMP_MAX which says how many tmp. files can be opened at a time.

Should be fixed with git commit a592f55473226f5bf91538359516623a0cdfea77
