Summary: resgen task fails due to file lock

Initial Comment:

On a Bi-opteron, dual core, XP Pro SP1 we get the following exception while executing resgen task (within csc or alone, and it does not depend on the number of resx compiled):

resgen tasks fails:

Cannot delete file 'C:\temp\tmp219.tmp\ResGen.exe'.
     Access to the path "C:\temp\tmp219.tmp\ResGen.exe" is denied

The Resgen.exe is actually copied in the .tmp directory.
We only run one instance of nant

With nant-0.85-nightly-2006-04-30 the script fails about 1 time on 2

With nant-0.85 it always fails but not always on the same resgen instance.

Could this be due to multithreading ?

The code in ResgenTask and ExternalProgramBase does not catch temp files
deletion failure.
failonerror=false is not sufficient to catch the exception
We resolved the issue by catching exceptions in the aforementioned
classes.
We also added temporizations to limit exceptions.
I don't have the code at hand but it was rather straightforward.

The IO problem should not occur normally, but there it seems to be due to
unstable hardware.

Additional Info - my 'fast PC' resgen situation is under Visual Studio
2003 under Windows XP SP2

I have the same resgen problem. It prevents us from upgrading from nant
0.84 to nant 0.85.
The code compiles ok under 0.85 on a PC with Intel Pentium II processor
993 MHz.
But the code compile fails under 0.85 with the ResGen problem on a newer
PC with Intel Xeon CPU 5140 @ 2.33 GHz.
Nant 0.84 successfully builds the software on both PCs.
