It means that no interrupts are serviced until they are enabled again.
You probably don't miss any, unless you overrun due to blocking for too long.
See my last breathless post on this:

and search for "interrupt" on this list for more...

What is the meaning of "interrupts are disabled"?
Interrupts are disabled when using atomic sections:
atomic {
...
}
On the MSP430 micro controller, does this mean the interrupts will be
delayed after the atomic section, or simply be discarded?
The same question for maskable interrupts: while a maskable interrupt
handler is under execution, a new maskable interrupt comes - in this
case, this new interrupt will be "disabled". Does this mean the new
interrupt be discarded or delayed?
In what case will an interrupt be lost?
Thanks a lot!
