Comment (by mcs):

 Here is the commit log (CVS revision 1.23) that shows when the concept of
 writing to disk first landed in the Mozilla code:

 http://bonsai.mozilla.org/cvslog.cgi?file=mozilla/widget/src/xpwidgets/nsTransferable.cpp&rev=1.23

 Unfortunately, this is ancient history and there is no reference to a bug
 number.  And the check in comment does not say why they changed things to
 write clipboard data to disk rather than keep it in memory.  My best guess
 is that they just wanted to ensure that memory usage stayed as low as
 possible.

 I think your proposed fix is OK.  It might be better to add a preference
 or a compile-time method to disable the WriteCache() code (Mozilla would
 be more like to accept a patch that uses such an approach).  For example,
 the kLargeDatasetSize value could be retrieved from a preference and a
 zero value could mean "never write to disk."
