in MySQL if you have tables MyISAM they will ignore all rollback
commands you exexute, so you will have inconsistencies in databases...
worst, if you have tables MyISAM and tables InnoDB the first will
ignore all rollback commands and the laters won't...
of course the legendary speed in mysql can be obtained if you use
tables MyISAM :(
some other issues (some of them had been resolved in 5.x i don't know wich ones)

one last thing mysql team doesn't afraid to change behaviours between
minor releases, look at this thread
