[Tracker] Memory allocation failures during extraction in 0.14.2

[Ken Schmedding <schmedk gmail com>]

Greetings,

I was getting these failures (as reported in tracker-extract.log in verbosity debug) on large files during extraction:

GLib:gmem.c:239 failed to allocate xxx bytes

I did some analysis and found that tracker-extract.log reports:
       Setting memory limitations: total is 18.4 EB
       Virtual/Heap set to 268.4 MB

I was confused by this as my Mac Pro running Fedora 16 has 12 GB of memory.  Also I was confused by the EB reported for memory as I never heard of E bytes

In tracker-os-dependent-unix.c line 284 I see a comment that seems to indicate I should get a virtual/heap of 1/2 of MAXLONG or about 1 GB instead of the reported 268.4 MB.
For testing I altered line 285 to not use CLAMP and set the virtual/heap to G_MAXLONG / 2 and after recompiling I now have a virtual/heap of 1.1 GB

All my memory allocation errors then disappeared.  Has anyone else seen this?  

Thanks,

Ken Schmedding
