>Description:
On some occasions, pkg_add will hang indefinitely. Inspection with gdb shows 
that it hangs in mpool_get, possibly in the loop inside mpool_look, although I 
couldn't get that information.
>How-To-Repeat:
It seems to happen at the same file every time in a particular package file, 
although there is no pattern to it.

db4 and perl are the only packages so far that have given me problems.
>Fix:
In order to attempt to find more information about the problem, I recompiled 
pkg_install and libnbcompat with -O0 and -g3, the problem seems to have 
disappeared after that. This is merely a workaround although it may point to 
what the problem actually is.
